Bonding/fixing plastic

[Wildfire]

I have a mounting lug broken off a headlight. What's the best way to bond it back together?

I've seen some loctite epoxy for bonding plastic or A hot airgun plastic welding kit?

The welding kit is pretty expensive though.

It's still cheaper than a new headlight but I would like to make sure it doesn't break again.

Any advice is welcome.

Cheers
