How can I get my scooter's headlights and taillights to be brighter?

by Randy Roark
(Gary, Indiana)

My gy6 150cc scooter's headlight and taillight are real dim at idle but brighten up when I rev the engine. I have replaced the stator, cdi, and regulator.

What could be the problem? Do you have diagrams of the wiring for taillights and headlights? Maybe there is a bad ground somewhere. Thank You!

Xenon Bulbs NEW
by: Blake

Some scooter companies now make Xenon hyperwhite bulbs for scooters. Check to see if they can help, or if you know the sizes bulb you need, try Google or your local parts store.

Hope I was able to help!

dim lights NEW
by: robert

Your scooter likely has no problem with the lighting system. the only thing you can do to improve the brightness of the bulbs is to slightly raise the idle. The lights are ran by the charging system, and as you noticed the lights get brighter as you increase the rpm. This is because the stator output increases with the rpm. this issue is very common in vintage vehicles.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.
