I put aftermarket led taillights on my 2019 chevy 1500LD LT 5.3l and the left turn single hyper flash when lights are on all bulbs been upgraded to led except the headlights are stil hid. Wondering if i clean the resistors and put dielectric grease on them and spray with fluid film. Will it protect the expose resistors? Second winter for them first winter no issue.
What resistors?
Probably talking about the load resistors that come with some LEDs.
Just use the original equipment bulbs and you won't have any problems.
Use the original bulbs as Doc said, or find LEDs that have resistors built in if you insist on the mod. Imo, it's not worth the hassle of soldering in resistors to keep the resistance in the circuit the same as the computer is expecting for the incandescent bulbs you took out. The LED has next to no resistance, causing the bulb to take very little power (wattage) to activate. that's why they quick flash when you have them in there. A blown incandescent bulb takes no power because the burned filament basically does the same thing. No power can flow through the bulb. The computer's trying to alert you to a burned out turn signal bulb, even though it's not, it wasn't designed to recognize the LED's tiny power draw is in fact a working light.
I would recommend the CANBUS style LEDs for your tail/turn/brake lights and front turn indicators. They work a lot better than the standard LEDs and they eliminated my hyperflash issues on both my Xterra and Mustang and they don't require external load resistors. They cost more though.
