For those who don't know, I have Depo 'quartz black' rear lights on my MK4 hatch:
Today I was followed then pulled over by a non-traffic policeman, who said he felt my rear lights were not bright enough, specifically the brake lights being too dim. He initially raised the issue of no reflectors in the lights, however after pointing out the two reflectors on the mudflaps he said he'd check with 'traffic' if that was allowed...this meets MOT regs so shouldn't be an issue, however he did think my brake light brightness wasn't high enough.
I've been followed by enough friends (including Ffoeg!) and nobody has commented on the rear lights/brake lights being dim, and I don't think they are, but I can't find anything on required brightness levels.
I got no producer etc. but they are going to get back to me with info on their stance on my lights...should prove interesting!
Does anyone know the regs. on rear light brightness? Can I get brighter stop/tail bulbs for the MK4?
