Yeah, we deal in 3M ClearBras as well but I strongly discourage trying to install one of those yourself and will take it a step further and likely decline selling one to you so I don't lose a friend. They're really, really difficult to install for a first timer. Kinda like idly noticing the car in front of you has an obvious home tint job, the DIY clear bras will look like crap even for someone who's had prior experience say with window tinting - the closest thing skill wise. These are WAY harder as the material stretches, which means puckers, etc, AND it has a powerful adhesive on the back. A recipe for you to get halfway done and have all manner of finger marks, bubbles, wrinkles etc and get so pissed off you'll just toss it in the trash in frustration.
Also, someone asked me for a photo of them. The whole concept behind the 3M product is invisible protection and you simply cannot even see that they're on from a foot away. You literally have to run your finger around the headlamp to feel the edges to even know they're there. So a picture will show, well, an 80 headlamp. They're 14mils thick, which is the thickness of about 5 sheets of paper.
The bummer with the acrylic lense covers shown above is that they get dirt between the headlamp and the cover - requiring removal and cleaning in foul weather just when you'd not like to be out.
