Light force spot lights

tried contacting Lightforce?? they have a great warrenty repair dept...

HArts paint shop at newman road geebung have a kit for plastic welding works well if don,t have it try protect auto paint supplies they have em too same place just 2 doors down cheers chris

I had a minor problem with one of my light force XGTs after over 50k klms on corrogated roads, They replaced the complete unit. They are proud of an excellent Australian product. Cheers Rob

I would go back toLightforce and show them whats happened. They sell their lights as the toughest, even shooting them swith a shotgun to show how tough they are, They'd maybe come good with a replacement.

If desperate find a company that repairs plastic bumpers.

You need to know what the housing is made of. The housing might be made of ABS, PC, PMMA, PP or numerous other plastics. Most common is ABS filled with glass fibres. It should be moulded into the housing somewhere.
I suggest that you try using toluene or chloroform (trichloromethane). I am not sure if these are available to general public, but you may know some industry sources (people) who could get you some.
The toluene is often sold as hobby glue, as it disolves pmma (acrylic), and other thermoplastics very quickly, and then evaporates and in effect glues two pieces together. But the housing may be a thermoset polymer, in which case solvents will not work, and you need binder. Something like slow cure epoxy, but then you need to uv proof the epoxy with paint or laquer.
This way you should overcome any uv problems, as you have not bound the parts with a resin.
And certainly paints will help, as long as the substrate will accept it. You need outdoor paint or laquer as these have high amounts of uv stability. You may need to do same flame ionisation to the surface, to improve keying and surface energy. Or you could do some solvent etching of the surface too.
No simple answer without knowing what the cracked housing is.

Hmmm. this is why I have cibbie oscars. Steel, not plastic.

I saw a 100s cruiser yesterday with two stubbie bits of broken plastic where his lightforce spotties used to be. OOPS.
