What's the Word

Seal It Up: Retrofit left the back side of your housings a bit open to the elements? These rubber housing caps may be your perfect solution to close that back up for good.

Sizing: Available in four different diameters to fit the most common headlight flanges: 75/80/90/100mm (internal diameter)

To Measure: Measure the outer diameter of your headlight's rear flange and select from the size menu above. If you're over by +3mm, we recommend going for the next size up and using a large zip tie to secure them.

Durable: Made of durable black rubber, they wont harden or crack over time through from hot and cold temperature changes. Ribbed inner ridge works to keep them fit snugly to the backside of the housing.

What else? Well...that's about it. They're rubber, they're housing caps, they keep crud out of your custom headlights. If you have a gap, you probably should order them. That's all!

Focus: Since 2005, we have focused our efforts on lighting and that's it. Experience means we know the products. We know the technology. We know our competitors, and most importantly, we know our customers. We like to wrench. We like to drive, we like to ride, and like you: we demand the best for whatever it is that gets us going. That's why at LED Concepts; we only stock the shelves with today's best, brightest, and most badass LED Lighting upgrades.

This was the perfect addition to install projectors on my 2006 Yamaha FZ1 since the projectors stick out the back of the light. Water tight now.

I had to get these to finish up the retrofit on my 2005 C230. I purchased the 90mm and fit over nice and tight. I secured them with a large zip tie and they've held strong since.
