Flasher Relay mod for LED bulbs.
 
Took a little work to figure this out, so thought I'd share for anyone interested.

The flasher relay can be modified pretty easily to flash at a normal rate with LEDs.

2x 1-ohm resistors (in parallel) are put in series with the 30-milliohm sense resistor, so the U243B chip detects a higher voltage drop and flashes normally.

Note that this makes it no longer function and possibly overheat if you use normal bulbs, but it is easy enough to undo or even drill the relay casing and wire a switch to change between.

I was just thinking about this the other week, ive been putting off installing high output leds because i was sure that the light controller would still get ticked off with the "open circut" nature of leds when they are off.
