i own quite a few sets and im looking to do some HID conversions in them. but im afraid that they will melt with the extra added head since they arent made of metal. and im doing the 55w HID's... not the 35w ones.

anyone tried it yet? or am i just gonna try and see what happens?

Rowhard converted the Hella Micro DEs to HIDs in the front round marker lights, but I don't recall if the Hella housing is plastic or metal, and I realize they're way smaller than your planned lights, but he may have some wisdom on the subject...
