Double Rubber housing
As the name suggests, this rubber housing is developed for mounting dual tail lights.
It's suitable for rectangle-shaped tail lights like the IZE LED, Briod, and others
We ourselves use these rubber housings for our tail light installations and, since we only use products we trust, we can confidently recommend these.
Available in two models; this double model and a single model designed for one lamp.
You'll find lamps in various specifications that fit this rubber housing under Lighting -> LED Taillights.
