So what kind of lights are you running?

I once made the mistake of putting Xenon bulbs in my 2004 Mustang GT fog lights...... That plastic didn't take kindly to the heat.

Ultimately, the optics are what make the difference and tend to be a “get what you pay for” equation. Halogen bulbs (with proper power) can look great if you get the right optics. IMO, nothing beats a quality true projector. Once you try it, there’s no going back.

There’s different kinds of “xenon” bulbs. 
HID lights use xenon gas, and have been referred to as “xenon” lights. They use an electric arc and plasma stream to create light instead of a standard incandescent filament. They produce a ton of light and heat.

Then there’s the incandescent “xenon” lights that are just a standard incandescent filament halogen bulb but filled with xenon gas instead of a “lesser” noble gas like argon. It does a few things for colour output. The different density of the gas around the filament makes for different light transmission properties. 

I’m pretty sure that’s all the Wagner xenon sealed beam lights previously mentioned are. Presumably a sealed beam bulb’s housing would be able to take any heat the bulb itself produces.
