Hi, since I have already equipped the interior with LEDs, I would know that this is not allowed, at least the rear driving light would like to exchange for a really bright LED. (so that I can see something in the dark) Now the illuminant is a P21W (12V). Probably 4 watts. If I now use a high-priced, 30 Watt Cree LED with reflector cone…I wouldn’t want to try it alone from the Watt base at all. Heat, smorgasboring, fire… But I don’t want to use such a 5 Euro LED from the bay either, because the light yield was rather sad and at some point you noticed that the board slowly but surely also freaked out, because it always got very hot. Or the brake lights with a P21W LED…has someone tried something like that at you times? I have seen this time at a V70 II. You have then very clearly seen that the front man slows down. I thought that it was good… As told, to me that this (unfortunately) is not allowed. So I would like to ask myself.
