Review on Super Bright LED Bulbs With 2X800 Lumens - 1157 2835 33-EX Chipsets - Compatible With Turn Signal, Tail And Red Lights - 1157 2057 2357 7528 Variants by Kyle Collins

This may useful for someone else exploring an illogical electrical ground issue specifically with Airstream trailer lights, in my case, after I replaced everything with LUYED LED lights. The Red and White lights of this same model didn't cooperate with my tail/brake/turn signals as they would not ground and drain into the skin of the trailer and either dimly blink the running lights and other turn signal and illuminate correctly as a running lights/tail light/brake light or if I twisted the bulb and maintained contact it would blink correctly, but would not illuminate as a tail light/running light. I replaced with an incandescent bulb and everything worked correctly. I then replaced the bulb (4 times with LED red) it would be the same issue vice-versa with certain bulbs with which the contact was made inside the socket making me deduce it was circuitry in the red LED lights after I spent days checking the wiring on the Airstream with no issues. So I tried white.fail. THEN I used a yellow, and it worked correctly with no ground issues. I ended up liking the yellow with the dark red cover as it makes a brighter red/orange. If you have illogical ground issues after installing these consider this case, and explore some other bulbs before you rip apart your trailer looking for bad grounds. Hope I save one other poor soul out there from a huge headache.
