We have extensive fitting guides - unfortunately they are all in printed format -

If you need to know what type of bulbs fit your car or bike please email us stating the make, model and year and we'll get back to you by the next working day. Otherwise please have a look for your model in tehse popup fitting guides:- H1, H3, H4, H7, HB3, and HB4

You could also have a quick look in your car or bikes owners manual - all bulbs are usually listed in there.

Alternatively take out an existing bulb, a H1 has 1 metall connector, a H4 has 3, a H7 has 2 and a H3 has a single connector on a short wire. HB3 and HB4 have right angled plastic bases - let me know if your not sure which you need!
