42mm: GTR Lighting 360-degree Festoon

Product Details

Complete Coverage: With 360 degrees of bright illumination, you'll get complete coverage and be able to see better than ever with these Festoon Bulbs from GTR Lighting. They're built tough and are packed with the technology to handle any workload you have for them for years.

Design: To begin with, these Festoon bulbs are created with the uniform opaque shell you see around them. Not only does that create the clean lighting you get from them, but it also keeps them free from hot and cold spots. In addition, it protects the internals so that they can be used anywhere. Finally, they're built with Canbus integration so if your vehicle tends towards bulb out warnings when you use LEDs, this solves that problem without additional wiring or resistors.
