Have these bulbs replaced with the original reversing lights in our camper, since the original lamps to light brought little while reversing. Because these bulbs are slightly lighter than the 21 Watt incandescent lamps this is now much better and you can also see where one breaks forth. Have additionally two LED - lights fitted to the rear, which come on the reverse with, now everything is wonderful. In a normal car, I would imagine this Leuchetn very good. Should I again have such a problem, I'll be back to access it.
