PROPLAST PRO-STAR 40100004 Truck Position Light
Your marker light is cracked. Or dead. Or full of water. The PROPLAST PRO-STAR 40100004 truck position light solves it. £18.50 each. 12V or 24V. Red or white LED. P&R rated. Fit it and forget it.
What Is the PROPLAST PRO-STAR 40100004 Truck Position Light?
How the Dual-Voltage LED Works
The 40100004 runs on 12V and 24V systems. No step-down converter needed. Plug it into a DAF at 12V or a Scania at 24V. The internal driver adjusts. Red light for rear position marking. White for front or side. 500mm flying lead gives you wiring slack without extensions.
Why Truck Position Lights Fail
Water ingress kills standard lamps. Vibration cracks cheap housings. Bulb types blow filaments. The 40100004 uses LEDs. No filament to break. The housing is sealed. P&R marking means it meets ECE R48 and R10. Road legal across the UK and EU.

FAQs
What does remanufactured mean on this product?
PROPLAST takes original housings, strips them completely, fits new LED boards, new lenses, new cables, and new seals. You get a fully functional lamp at a lower price. The EAN 4025091419261 identifies remanufactured stock.
Can I mix red and white on the same 40100004?
No. The LED colour is fixed at manufacture. Red units show red. White units show white. Order the colour you need for each position.
Is the 500mm cable long enough for my trailer?
Yes for side markers. For rear position lights, splice extension cable using waterproof butt connectors. Keep total length under 2 metres to avoid voltage drop.
Will this pass a UK MOT and annual trailer test?
Yes. P&R marking confirms ECE approval. Position lights must show steady light to the side and front/rear. The 40100004 meets both requirements. No flashing permitted on position lights.
I have a 24V only system. Will this work?
Yes. The 40100004 runs on 12V and 24V automatically. No switches. No converters. The driver handles both. Position Light
