Hello and good day, since the Fern/Abschlendlichter on my bus (a B611 year of construction 61) or my Volvo P1800ES are very modest especially in bad weather conditions, I had to mount two additional headlights or fog lamps on the front-stump. I searched for headlights in the period of the 60s – 70s and also found some models. Installation is no problem, but I have a few basic questions about this now: For many models ga In addition, there was the option “white light” and “yellow light”, where the lamps have yellow glasses, and that for driving light and fog lamps. In ECE R48 §6.1, R98 and R112 it is mentioned that driving light may only be white. However, for fog lamps (ECE Regulation No 19) this exception does not apply. t and can also be light yellow. But what does this look like now with vintage cars? Obviously there was also yellow additional distance light in the 60s-70s. For fog lights (usually) a tint over the glass is not allowed. Obviously this was earlier however different. There are even yellow-tone lenses (e.g. Lucas etc.) that could be mounted on the existing lamps. Is the operation of such “historical” driving light lamps or fog lights with yellow glasses on a vintage car from the The same epoch is still allowed, or is it an issue with every control? And what does this look like when retrofitting clear glass with “yellow” illuminants? I’m looking forward to your answers.
