If you have some rectangular H4 halogens in your RV-4 or RV-6, our new adapter plates will make replacing them with our our Double Spotlight boards a breeze.
The kit consists of one adapter panel and four 1.5" screws and spacers. The plates have mounting holes drilled at 5" spacing, the same as on your plane.
If you have two lights, you'll need to order two parts.
Paired with the Double Spotlights, this is the simplest option to upgrade your halogen landing lights.
