Mexican washboard is hard on filaments.
Practically Parked in a traffic jam is hard on LED brake lights.
Not much air circulation inside the housing or behind it and it still seems that bright LEDs equal hot LEDS = short lived LEDs.
Perhaps more dielectric grease in receptacle can help draw more heat from LED bulb base, and sticker the backside with mini heatsinks
I keep 3196 2057 and 1157 incandescent spares on hand, but my 1157 red LEDs are still Ok at about 2 years. I do not even have to leave vehicle to replace them.
