hi all - ive just bought 2 roadster spot lights - to mount either side of my headlight - there is no wireing diagram - so im asking if anyone knows how to wire these to the full beam of my headlight? there are 4 wires coming from the spot light - 1 thick black 1 thin black - 1 thin white and one white coated wire ( like the green earth on a plug ) also is it legal to wire these to my headlight full beam ? or should i be putting in another switch just for them? any help here would be great - or if anyone is local and fancys a run out to help me sort this - id owe ya one - i would say theres plenty of booze for ya - but with rideing out - i better say the kettles never empty - lol                                                                                                                                                                             

Dont see any reson why thay would be the same as main beam assistors as for wiring best get the main beam surply wire checked so you dont over load it and fry your loom                                                                                                                                                                              

Are you able to wire them in via a relay?

Add another fuse to the fusebox and wire them in through this with the "switch" being the relay running off the main beam circuit.                                                                                                                                                                             

now thats way over my head and beyond my know how looks like i'll have to take it to a garage and get the pros to do it :-(                                                                                                                                                                             

If in doubt Photographer, that's the answer. As JP suggests, electrical fires aren't fun!                                                                                                                                                                             

All I know is the ones on my Landy are wired up to the main beam and thats fine, and they are wired up through a relay. I only had two wires coming out of mine so do you have the type which has a side light in them as well as the spot.?

theres only 1 bulb in the light so i dont think it has a side light - just 1 spot 12v high quality halogen lamp - but i think isnt going to be 2 hard for me to sort - i will fix them on and then take it to someone that knows what there doing - but thanks for the help guys

try emailing practical sports bike mag ask the question to go to ferret  he's the man apparently
