Bulbs for Trucks, HGVs and Trailers
Maintaining correct lighting on a commercial vehicle is a legal requirement, not just a maintenance task. Truckstop stocks the full range of bulb specifications used across the UK truck fleet, from headlamp H4 and H7 units through to side marker, indicator, reverse and interior bulbs. Brands include Hella, Osram and other OE-approved suppliers.
Finding the Right Bulb for Your Vehicle
Commercial vehicle bulbs span a wide range of cap types, wattages and voltage ratings. The 24V fitments used in most HGVs differ from the 12V equivalents found in vans and light commercials, so specifying the correct voltage alongside the bulb type is essential. Truckstop lists full specifications on each product, and the trade team can cross-reference against make, model and year where needed.
What bulb types are available for commercial vehicles?
Truckstop stocks H1, H3, H4, H7, H11 and R5W fitments alongside P21W, P21/5W, PY21W and BA15S types, all in 24V ratings for HGV applications. Side marker, clearance and trailer bulbs are also stocked in T10, BA9S and festoon formats commonly found on trailers and older builds.
Do you stock bulbs for specific truck makes?
Yes. Many bulbs are cross-referenced to specific makes and models including Volvo, DAF, Scania, MAN, Mercedes, Iveco and Renault. Where a fitment is make-specific, this is noted in the product listing. If you cannot find a match, contact the Truckstop trade team with the vehicle registration or chassis details.
What is the difference between 12V and 24V bulbs?
12V bulbs are standard for cars, vans and light commercial vehicles. 24V bulbs are required for most HGVs and trucks. Fitting a 12V bulb in a 24V circuit will cause it to fail immediately. Always confirm the system voltage before ordering. Products listed in this range are 24V unless otherwise stated.
