my lights are dim and only brighten up a bit when you rev.i put on a set of spots and a 55w bulb in the headlight but they are still dim.could it be my battery as its smaller than the original.everything else works just fine

Hiya Skikman.

Welcome to the forum

Could you tell us more about your bike? Things like; what it is, how old it is, what mods there are.

It'd help us help you

its a 2003 lifan lf 125-a custom a copy of the honda cm 125.i would post a pic but dont know how

OK, that helps.

If the battery is more than 3 years old, I'd be considering that first. Especially if your bike has been parked outside a lot. Though if you've got a multi-meter (and the specs of the alternator out puts) checking how much is coming out of the alternator would be worth doing.

After that, it could be the wiring and/or contacts/multi-plugs might be getting tired.

Keep us updated mate.

Welcome skikman!

The best thing for dim lights is to send them to a better school!

the bike would struggle with just an uprated bulb, never mind additional spots.
my advice, dump the spots, get the battery checked out & the alternator output, if they are ok then go back to the origional power H/L bulb & learn to live with it.
these bikes are built to a (low) price, you cant expect them to cope with extra lights-especially if you have a smaller battery than standard.
