Hi, I am having a problem with my speed fight 100 and hoping someone may be able to push me in the right direction before I take it to a mechanic! Main beam has never worked, always blows as soon as its switched on but I'm used to normal beam so not a major issue at the moment but yes it does need fixing! My headlight works for about 2 minutes then cuts off..if I leave it with engine off sometimes it will come back on but not often, sometimes the bulb has blown completely. I've charged the battery, cleaned all connectors, checked the switch, I just can't find why it works then stops? Any idea's? Also I am using the correct bulb as per manual suggests
