Here's what I use from
superbrightleds.com :
Front Blinkers: 1157-x18-T (Amber)
Rear Blinkers: 1156-x18-T (Amber)
Tail Light: 1157-x45-T (Red)
Instrumentation: Ba9S-WHP (Cool white)
Blinker Relay: LF1-S-PIN
*You could probably use the "CBT" models over "T" for blinkers and save about $40, but I would still go with the 45-T for the tail light. If you're not using the fronts as running lights just get 1156's for all 4. The relay for some reason you need to reverse the black and grey wires if memory serves correct. These are bright and look great. I have the same setup on all 3 of my bikes. This place is also good for getting replacement socket bases.
