LED front marker lights for trucks and trailers
Front marker lights on HGVs and trailers must be white, positioned as close to the outermost edges of the vehicle as practical, and must carry E-mark approval. They serve as front position lamps and are required under ECE Regulation 48 on vehicles over 6 metres in length. Their function is to indicate the vehicle's presence and width to approaching drivers, particularly in low visibility conditions.
LED front markers have replaced incandescent marker lights on most new builds. The advantages are the same as for side markers: lower current draw, longer service life, and better resistance to vibration-induced failure. On multi-axle combinations where the cab and trailer each carry multiple marker positions, the reduction in total electrical load from switching to LED is significant.
Marker lamp condition should be checked as part of any pre-journey inspection. A failed front marker is a roadworthiness defect that can result in a DVSA roadside prohibition. Keeping replacement markers in the cab is standard practice on long-distance operations.

Frequently Asked Questions
What colour do front marker lights need to be on an HGV?
Front position markers on HGVs and trailers must be white under ECE Regulation 48. Side markers must be amber, and rear markers must be red. Fitting the wrong colour at any position is a roadworthiness failure. All front marker lamps in our range are white and E-marked for UK and European road use.
How many front markers does an HGV need?
Under ECE Regulation 48, vehicles over 2.1 metres wide require front position lamps positioned as close to the outermost edges of the vehicle as practical. For most HGVs and trailers, this means two front markers, one at each side. Check the regulation and your vehicle's type approval documentation for the specific requirements for your vehicle category.
Do LED front markers need to be E-marked?
Yes. Front position markers fitted to commercial vehicles and trailers used on public roads must carry an E-mark confirming compliance with ECE R7 or equivalent. Non-E-marked LED markers are not roadworthiness compliant and are likely to be flagged at DVSA inspection. All markers in our range carry the appropriate approval marking.
What mounting configurations are available for LED front markers?
LED front markers are available in side-cable-entry and rear-cable-entry configurations, and in both low-profile and standard-depth bodies. The choice depends on your mounting surface and cable routing. Side-entry is the most common for bodywork rail mounting where the cable runs inside the rail structure. Confirm the configuration before ordering, as swapping entry positions after fitting requires re-routing the cable.
