Yeah, the LED tail/brake light thing rears its ugly head again. After much research, these are the bulbs I want to go with, but there seems to be little to no info on whether or not I will need a load resistor or a new flasher relay.
This will be for a 68 Coronet, and I'm only replacing the bulbs in the tail... the front signals will remain incandescent. Thanks!

Electronic flashers are cheap and easy.

Yes, you will need an electronic flasher, as the LED do not draw enough current to allow the old style flasher to work properly . .

Also need to note they have a polarity, so if it doesn't work, you might have to swap the two wires - simple fix !
