    Hi all,

    new to the forum, just sold my gsxr 600 and fancied a bit of a project so have picked up a 1978 honda xl 250 (although the insurance company seem to think its a 75 but anyway...)

    Rode it home through London in the pouring rain and it was brilliant, engine seems solid and generally its in pretty good shape, the only thing bugging me is that when i brake the rear light turns off rather than illuminates!

    im going to have a proper session in the garage with her over the weekend but wondered if anyones had this problem before? i thought it could be a bad earth somewhere?

    ill get some pics of the bike up over the weekend. thanks.

    the bulbs have two filaments. chances are you just need a new bulb. only god knows how old that bulb could be!

    ill see if i can find one somewhere, may as well have candles for all the good the lights did! im thinking of just getting a daytime mot and making her into a CR race rep or something similar, either way for it to be legal i still need a working brake light, thanks for the quick reply.

    A weak battery will cause all kinds of problems too.

    You didn't mention if it was happening with both the rear and the front brake. If it is just the rear its possibly the rear brake light switch adjustment. On those old Hondas the rear brake light switch had a weird quirk. If it was poorly adjusted when you pressed the rear brake pedal the light would come on but if you kept pressing it would go off again this was especially true if the rear brake pedal had a lot of movement because the brake also needed work. Similarly if its even further out of adjustment the brake light will be on all the time and when you press the pedal it goes off. The front brake light switch was not adjustable and didn't have this problem.

    I own a 75 XL350 it has no front brake switch, to activate the rear brake light . yes,it most likely has a bad rear brake bulb, may as well get two bulb's.:D:D:D

    great thanks for the advice, i think its just the rear brake, as im driving along the light stays on then press the foot pedal and the light comes off, ill get some new bulbs and check the connections etc...then its a case of stripping the lights, speedo, unwanted weight and turning it into a CR rep type thing.
