I have always been unhappy with the brightness of my lights on the back of the camper. I took off the covers and put aluminum tape in the housing of the light behind the bulbs and it made a world of difference. They are much brighter and safer now.

I wonder if you could add some of those LED replacement bulbs. I have heard they are brighter than the originals. Those LEDs and the tape would really make them bright.

I don't know I guess you could change to led, but they are very bright now and a lot cheaper than changing over to led.
