Diode Dynamics 20mm Breather Patch

 

Diode Dynamics 20mm Breather Patch gives customers resealing, retrofitting, or venting headlamp and tail lamp housings a simple way to let trapped air escape while helping block moisture from entering the lamp. It is made for customers who want better airflow inside the housing and less risk of condensation after lighting work without turning a lighting upgrade into guesswork.

The adhesive patch covers a drilled vent opening so the lamp housing can breathe without leaving a large open hole exposed to moisture. Instead of leaving customers to work around sealed housings that trap humidity after retrofit work, resealing, or temperature changes, it provides a small woven breather patch sized for a 1/2 inch vent hole for a cleaner result when a customer has opened a headlamp, replaced sealant, or wants better airflow in a lamp housing.

The round black patch measures 20mm in diameter and uses a stick-on application method. It is designed to be placed over a 1/2 inch hole, and two patches per lamp can be used when maximum airflow is desired. Customers can match the accessory to the light, housing, circuit, connector, or vehicle application before installation begins.

The patch is offered in smaller and bulk quantities so customers can handle a single lighting project or keep extra patches available for multiple lamp housings. Universal fitment makes the patch useful on many headlamp or tail lamp housings that have a flat surface for placement. The right version helps the finished upgrade stay cleaner, easier to service, and better matched to the job. Careful preparation, secure connections, and clean placement help the accessory perform as intended after the installation is complete.

Whether customers are upgrading for headlight restoration, retrofit work, moisture control, or resealing projects, the Diode Dynamics 20mm Breather Patch delivers a clean and compact venting solution for lamp housings. Now Available at LEER!
