No way you're installing longer bulbs on mine without pulling the lights, I'm pretty jealous that anyone has enough slack to do that.
So I did what
@

said. Installed rear resistors and rear LED. Here's the outcome:
1. LED turn signals work without hyperflash, but I have to use the Lasfit bulbs in the front
2. the nothing fancy, non-CANBUS bulbs hyperflash when put into the front turns
2. DRL no longer works at all with any bulbs
In the rear, I tapped the yellow on LH and light blue on RH for +, as these are the only wires that read on the meter.
