The Sprint is designed so that it can have both dipped headlights on or just one. Depending on the country regulations Triumph either install all 4 relays for both headlights or just 3 relays for one headlight. In the USA the regulations require both headlights, here in Aussie only one dipped is required by law, do not not know what Triumph can get away with in the Old Country. Most of us in Aussie fit the 4th relay to give better lights when the current bun goes down, it also means we have a better chance of being seen by the OTHER road users.

The relays are mounted all together inside the right hand fairing, you can see them but replacing them requires touch and feel especially if the rubber mount comes off the bracket. The series of photographs below will give you a good indication where they are mounted.

Now to your problem, the relay MUST be a diode protected type otherwise it could drain your battery or burn out. If your headlight bulb is ok, then I guess they fitted the wrong type of relay (no diode) the last time you got the shop to look at it.







The white one is the one I fitted to get both lights to on. Triumph will charge you a arm and leg if you get them to fit it for.
