My front bulbs are 4w when flashing and the rear bulbs are 3w when flashing.

Does this math look right?

(.42*2)/(3+4)=.12

I ordered a 1w 120mOhm but I'm still getting the fast blink. I guess I need to go bigger. I should have ordered several values rather than a single 120mOhm. Sucks to pay $4 shipping on a .33 resistor. Hahaha. It sucks not being able to buy stuff like this locally.

Edit: Thinking about now. Maybe I should only apply the math to the smaller bulb: .42/3=.14
I guess worst case I go to big on the resistor and I loose the burnt bulb detection which I am fine with.
