The headlight on the bike is not the best and the main beam is next to useless. Can anyone suggest a better replacement and possibly a cheep place to get it. Thank you. Take care

You can probably switch over to a more modern YBR headlight as they use Halogen as stock, or do what I did and find a direct plug in halogen replacement, they sell the bulb in Halfords. Just look for the correct connector. 

 

But at some point you have to accept that bike headlights tend to be a bit shit.
