LED single function lights for trucks and trailers
Single function LED lights are units designed to perform one lighting function only: a rear fog lamp, reverse light, brake light, or similar. Unlike combination rear lamps that incorporate multiple functions in a single housing, single-function units are used where a specific function needs to be added or replaced independently.
The Durite LED red rear fog lamp in this collection operates at 10-30VDC, making it suitable for both 12V and 24V vehicle systems. LED rear fog lamps produce a high-intensity red output to warn following traffic in conditions of reduced visibility. Under UK and EU regulations, at least one rear fog lamp is required on vehicles and trailers; the position and brightness requirements are defined under ECE Regulation 38.
When fitting a replacement rear fog lamp, confirm the voltage rating matches the vehicle system and check the lens colour (red is required for rear fog). The mounting configuration and wiring connection should also be matched to the existing installation.
Frequently asked questions
What is a single function LED light?
A single function LED light is a unit that performs one specific lighting function, such as a rear fog lamp, reverse lamp or brake light. It is distinct from a combination lamp, which houses multiple functions such as stop, tail and reverse in a single unit.
Is a rear fog lamp required on UK trucks and trailers?
Yes. Under ECE Regulation 38 and UK road vehicle lighting regulations, at least one rear fog lamp is required on motor vehicles and trailers registered for road use. The lamp must emit red light rearward and be capable of a defined minimum intensity.
What voltage are the LED single function lights rated for?
The Durite LED rear fog lamp in this collection is rated for 10-30VDC, covering both 12V and 24V vehicle systems.
Can a single function light replace a combination rear lamp?
No. A single function unit replaces one specific function only. If a combination rear lamp unit has failed, the replacement should be a matching combination unit, or the individual function can be supplemented by a single-function lamp where the installation allows separate mounting.
Can I get LED single function lights delivered next day?
Yes. In-stock units are available for next-day delivery to UK mainland addresses, or same-day collection from our branches in Redditch, Worcester, Birmingham and Evesham.
