I know that this setup is a LED based one, hence my original post (tell me voltages, I'll tell you what resistor would do the trick
:P ). The original bulbs work with a power usage of around 20W-25W with the standard relay, new circuit needs same power usage in total.
I didn't know that LED kits for bikes come with a built in resistor, but thinking about it, it makes sense otherwise customers would just get p****ed off buying resistors etc. In this case it'll need to obey the old Rt=(R1+R2+R3...Rn)/n principal.
Edit: Make that the Rt=1/((1/ R1)+(1/R2)+(1/R3)...+(1/Rn)) principal
