They are a joke on the bigger bikes too lol I’ve done a mod on mine that bypasses the wiring loom and goes direct from battery to lights via a switch and an auto relay its much brighter now as for your question not sure but I’ll bet your not allowed 🙁

Can’t see the question.

Lots of bikes have crap headlights unfortunately. You could bodge on extra lights but will not be road legal unless e-marked.

First thing to do is probably to upgrade the bulb to the best you can find for your fitment- think Osram Nightbreakers are probably still competitive but there might be better now.

There’s other options though… I used a (illegal) HID light conversion in my bike for ages. Definately a “ymmv” thing though- my bike had twin headlights and one side couldn’t be convinced to aim safely, so I removed the HID from that and went back to a Nightbreaker in that side. The other aimed well and was safe- passed 2 MOTs (though legally shouldn’t) and also various police inspections.

But equally you could spend a lot of money and just get something that works badly or even unsafely, so.

Lastly depending on your bike it might be practical to replace the whole unit with something better- if it’s an unfaired bike, that’d probably be straightforward assuming a 12V system.
