Switchback load resistor problem!
Ive seen posts stating that resistors placed in line for led conversions get hot, real hot. I have the switchbacks and the hyperflash adapter (flasher bypass) and everything works fine for years. I never really took the panel off and felt the hyperflash adapter so it might be hot, but as I said ....no problems thus far.
You might want to consider:
A) Leaving the resistors out, letting it flash faster and dealing with a little less bulb life (the on and off cycle is the most wear any bulb goes through).
or
B) Just adding the flasher bypass.
Route B also frees you from the possibility of the OEM flasher (which is behind the hazard switch in the center of the dash, and is a pain to get at to replace) going south as it bypasses that portion of the circuit.
FYI the bypass is a ten minute install, drop the panel under the steering wheel (three screws), plug it in and close it back up.
Good luck






I went that route from day one and never had any issues.
