I picked this idea up and ran with it. The test subject is my ratty car that I call
Jigsaw.
1970 Dodge Charger, taillight housings are all stock, these are incandescent 1157 bulbs with 1095s in each housing toward the middle of the car.
Tail lights:

This is with the left housing painted with white paint from a spray can.

Brake lights, same as above...the left side with spray paint.

House paint in both housings, tail and brake lights:

Finally, the right side bulbs were replaced with drop in LED bulbs....

How about night time?
Jigsaw on the right, my other Charger ( Totally untouched housings, silver paint as stock) on the left.
Tail lights:

I had nobody here to press the brakes in the cars so I enabled the flashers and tried to snap pictures as BOTH cars lights were brightest. Talk about trying to thread a needle....

Jigsaw is still noticeably brighter with the white painted housings.
Thanks to Daniel Stern for this great tip!
