Will this cause it not to work or will it just be that ifn I will no longer get hyperflash even if old bulbs are back in and blown?
Since you have LEDs in all the turn signals, you'll end up taking off a lot more than I did. I left the incandescents in the rear because I just wanted the LEDs in the front in order to reduce the heat from them being on as DRLs all the time.
I would try grinding it very thin in one spot if possible. If you grind too far, you can always solder back up. Not sure what would happen if you tried to use the flasher with the resisitive loop in open circuit. It might just flash without trouble, or it might burn up the IC. You might end up having to cut the loop and put a higher resistance wirewound resistor, similar to what the guy at the Ridgeline link did for his little Honda flasher.
I would suggest trying with an incandescent bulb in a front turn bulb socket (since it's easier to access than the rear bulbs) just as a test to see if you've gotten it ground down enough to work with 1 led and 1 incandescent bulb.
Has anybody else tried this with the same setup I've used here? (Incandescent rear turn signals with LED front?)
Oh, and I'm in Italy on business until next weekend, so I can't look at my truck till I get home.
