I made two aluminium housings that replaces our heat cracked plastic tag lights. When using a single 3/4" diameter LED light for each side,the light out would stay on. Throwed'em in the dumpster. Sooooo I then made up a dual angled housing fitted with two 3/4 red LED's for each side. No light out indicator now and no resistors! Even though they're out of sight,I painted the aluminium housings to match the car. Just to look cool when the trunk is open. Looks like the back of the car is on fire with the 4 LED's shinning thru the cold exhaust moisture. Should have a very long life being there rated for 14 volts and pull .05 amps each. Used on new18 wheeler's for marker and clearance. 3/4 " sealed 1 diode pattern. Truck-Lite 33250R Model 33. Squirrel Crusher
