Do it right: When installing halos, put down the epoxy! Pros know thin wire is the only way to do it right and hold it tight! Our house-brand copper based wire is whats up. Invisible: When properly installed, the beading wire virtually disappears into your headlight - making it next to impossible to see. Compared to using messy glue which can drip or turn yellow over time - this is the way to go. By the Numbers: Each roll is 10 meters long, which means you'll have more than enough to install several sets of halos in your headlights. The material is just .4mm thick, making it hard to see, yet strong enough to hang on forever. Installation: Drill two tiny (.5mm) holes in the surface that you want to mount the halo to. Loop the wire from the back, up over the halo (or using integrated mounting points) then back through the second hole and twist from behind. It's truly that simple to easily mount halos reliably for years to come!
