Dock lights and wheel guides are two simple loading bay aids. A dock light is a lamp, usually LED, on a swing arm beside the dock door that shines into the trailer so forklift drivers can see the load. Wheel guides are steel rails fixed to the yard that steer the rear wheels so the trailer arrives straight and centred on the leveller.
How much do dock lights and wheel guides cost?
Dock lights and wheel guides typically cost £280 to £950 per item, supplied and fitted, excluding VAT, where an item is one dock light or one wheel guide. A standard LED swing-arm light usually sits in the lower half of the range; long, heavy-section or cast-in guides sit towards the top.
What moves the price:
- Light specification: arm length, LED head output, protective guarding and whether a low-voltage supply is needed.
- Power: the distance to a suitable supply and how the cable is contained.
- Guide length and section: longer guides and heavier steel cost more.
- Yard surface: sound concrete takes anchors directly; tarmac usually needs a concrete base first, priced after survey.
- Number of bays: fitting several bays in one visit lowers the cost per item.
These are guide budgets. After a free site survey we send a written quote, which is the fixed price. VAT is added at the standard rate.
Which type of dock light is best for a loading bay?
An LED swing-arm dock light is the usual choice for a loading bay, because it reaches into the trailer during loading and folds back flat against the wall when the bay is closed. LED heads run much cooler than older lamps and cope better with knocks and vibration.
- Arm length: longer arms push light further into deep trailers, but need clear wall space so they can fold away from the door path.
- Rigid or flexible arm: a rigid arm with a pivoting head is tougher; a flexible section can be easier to aim.
- Guarding: a protective cage or polycarbonate cover helps the head survive forklift contact.
- Switching: a switch on the head or on the wall, or linked to the door so the light comes on as it opens.
- Supply voltage: mains or low-voltage, confirmed at survey to suit your site.
The light is mounted inside the building beside the door, clear of the door tracks, at a height that lets it swing over the leveller and into the trailer.
Should wheel guides be bolted down or cast in?
Wheel guides are bolted down on an existing sound concrete yard and cast in where new concrete is being laid. Both give a strong fixing; the choice depends on whether the yard is being resurfaced.
- Bolt-down guides: steel tube or channel fixed with resin anchors. Quick to fit to existing bays and easy to replace if damaged.
- Cast-in guides: set into fresh concrete with embedded anchors, suited to new-build docks and conversions.
- Flared entry: an angled lead-in at the yard end catches the wheel early and steers it into line.
- Finish: typically galvanised, or painted yellow and black so drivers can see them in mirrors.
Guides are set out to suit the track width of the trailers you receive, centred on the leveller, and long enough to straighten the trailer before it reaches the bumpers. Tarmac is usually too soft to hold anchors, so a concrete strip or base is laid first. Our guide to choosing dock bumpers and wheel guides covers layout in more depth.
Which types and options are available?
LED swing-arm dock light
An LED head on a swing arm beside the door, swung into the trailer during loading and folded back flat against the wall when the bay is closed.
Low-voltage dock light
A swing-arm light fed through a transformer mounted nearby, for sites that prefer a reduced voltage at the lamp head. Same reach and folding action as a mains light.
Bolt-down wheel guides
Steel tube or channel guides fixed with resin anchors into an existing concrete apron, typically galvanised or painted in high-visibility colours for drivers using mirrors.
Cast-in wheel guides
Guides set into new concrete with embedded anchors during yard works, giving a very strong fixing for new-build docks, resurfaced yards and loading bay conversions.

Do health and safety rules cover dock lights and wheel guides?
Dock lights and wheel guides support your wider loading bay safety duties rather than replacing them. Once fitted, a dock light is work equipment under the Provision and Use of Work Equipment Regulations 1998 (PUWER), so it must be suitable, maintained in a safe condition and inspected where deterioration could lead to danger. In Northern Ireland the equivalent is PUWER (Northern Ireland) 1999.
HSE's guide to workplace transport safety (HSG136) is the main reference for managing vehicles in the yard, and its loading guidance says there should be safeguards against drivers driving away too early, such as traffic lights, restraints or key control. Wheel guides and dock lights do not meet that requirement on their own, but they help drivers park accurately and help dock staff see what they are doing.
Electrical work for dock lights is carried out by qualified electricians and tested before use. The regulator is HSE in Great Britain and HSENI in Northern Ireland.
What happens on site when dock lights or wheel guides are fitted?
Dock lights are fitted from inside the building and usually leave the bay usable for most of the work, while wheel guides close the bay to vehicles until the anchors have cured.
- Dock lights: the bracket is fixed beside the door, the arm and head fitted, and the supply connected and tested. The circuit is isolated briefly during connection.
- Wheel guides: the yard in front of the bay is coned off, guides are set out, drilled and anchored, and the resin is left to cure before trailers return.
- Concrete bases: where tarmac needs a concrete strip first, the bay stays closed until the concrete has gained enough strength.
We ask you to provide a clear bay, details of the nearest power supply, safe yard access and someone who can manage vehicle movements around the work area. Planning guide installation for a quieter period keeps disruption to a minimum.
How do wheel guides protect shelters, seals and levellers?
Wheel guides protect dock equipment by keeping every trailer centred on the bay, so contact forces land where the equipment is designed to take them. A trailer that parks off-centre loads one side of the dock much harder than the other.
- Shelters: off-centre trailers catch the side curtains and frame, causing tears and bent arms.
- Seals: one pad is crushed while the other barely touches, leaving gaps for draughts and rain.
- Levellers: the lip can land near the edge of the trailer bed, with less support for forklifts.
- Bumpers: one bumper takes every impact and wears out early.
Dock lights help in a different way: forklift drivers who can see clearly inside the trailer are less likely to strike the trailer walls or the door frame on the way out. Combining guides and lights with correctly positioned dock bumpers gives a well-protected bay.
When is this the right choice?
- Forklift drivers struggle to see the back of the trailer or the load inside.
- Trailers often arrive off-centre, tearing shelter curtains or crushing one side of the seal.
- Drivers need several attempts to reverse on to the bay, slowing turnaround times.
- Leveller lips or door frames show impact damage from trailers parked at an angle.
- Existing dock lights use old lamps that run hot, flicker or are often broken.
How the job runs
- Site survey
We look at how trailers approach each bay, measure the yard and door surround, check the yard surface and find the nearest power supply for dock lights.
- Written quote
You receive a written quote listing each light and guide, the fixing method and any concrete work needed. The survey and quote are free and without obligation.
- Installation
Lights are fitted from inside with a brief electrical isolation, and guides are set out and anchored with the bay closed to vehicles while the resin cures.
- Testing and handover
Lights are tested and aimed into a trailer, guide fixings are checked and the bay is handed back with a note of any other wear we noticed.
Dock lights and wheel guides: questions
Where should a dock light be mounted?
A dock light is mounted inside the building beside the door opening, high enough to swing over the leveller and into the trailer. It must fold back flat against the wall, clear of the door tracks and the forklift route, so it is not struck when the bay is not in use.
How long should wheel guides be?
Wheel guides need to be long enough to straighten the trailer before it reaches the bumpers, and the right length depends on your yard and approach. Tight yards where drivers turn late usually need longer guides with a flared entry. We set the length and spacing at survey.
Can wheel guides be fitted to a tarmac yard?
Wheel guides can be fitted to a tarmac yard, but tarmac is usually too soft to hold anchors on its own. The normal approach is to cut out a strip and lay a concrete base for the guides. That work is identified at survey and included in the written quote.
Are LED dock lights better than older lamps?
LED dock lights are generally the better choice. They run much cooler, so there is less risk of heat damage to goods or packaging close to the head, they cope well with vibration, and they reach full brightness straight away. They also use less electricity for the same light, although savings depend on how long the lights are on.
Do wheel guides damage tyres?
Correctly spaced wheel guides should not damage tyres. They are set slightly wider than the trailer track so the tyre only brushes the guide when the trailer is off line, and a flared entry stops tyres hitting the end. Guides that are bent or set too narrow should be corrected.
Can dock lights be fitted without stopping loading?
Usually yes. Dock lights are fitted from inside the building beside the door, and the bay can often keep working except for a short period while the supply is isolated and connected. We agree timings with you so the work fits around trailer arrivals.
