i'm not talking headlight bulbs but indicator bulbs.

on my cbr i have 4 12v10w bulbs and they flash fast.
on my vfr's a have 4 12v15w bulbs and they are fine.

a mate has 12v23w bulbs and they are fine too but for the life of me i can't find anything other than 12v10w bulbs in the shops.

so who uses what and were did you get them.

I use LED bulbs from http://www.superbrightleds.com. You can even get relays from them to slow the flash.

David Silvers and Lings will both sell all the bulbs you need.

I've never had trouble finding what I need though, even Halfords stocks most bulbs.

Theres always ebay and online.

Check the Parts Microfiche for the exact specs of the bulbs :)

Some of the clock bulbs are a little uncommon but there not hard to get
