Questions and answers
Hi, where are the little lamps for in the headlight unit? They don’t light up
The little lamps in the headlight unit of a HYOSUNG GT 650 are illumination lamps with a wattage of 1.7W. If they do not light up, possible reasons could be a blown bulb, a faulty connection, or an issue with the electrical system. Checking the bulb, wiring, and fuse could help identify the problem.

@Mr. Anderson thanks for your reply. The lamp isn’t broken but just doesn’t illuminate. By the way I don’t know the reason for this little lamp because the headlight of a Hyosung 650 is always on, there is no switch to turn it off. For a car I know it’s used as a parking light. I hope you have an andwer for me.
