Review: As described, solid sockets - The sockets seem of good quality and when attached to each other, the joint is solid. Plus they snap together, that was a pleasant surprise. Good length wires, nice thick insulation. The black and white wires for the coil are advertised as 18AWG which seems like a waste because the coil of the standard 12V Bosch automotive relay draws only 150mA and 18AWG wires are rated for full 10A. One suggestion for the seller, if I may: in the picture with labels for each wire, you might want to label the blue wire (87) the "Normally Open" because that is the contact it is connected to and it would also be consistent with the yellow wire (87a).
Review: Works great - Perfect for my headlight assembly. Good quality.

## Features

- ORGANIZED - Interlocking design for easy cable management & organization.
- TOUGH AS NAILS - Our brackets are powder-coated, not painted. Powder-coating provides a more durable, weather-resistant, longer lasting finish than traditional paint can offer.
- ADAPTABLE - The swivel bracket is one of the most adaptable and useful brackets we offer. Perfect for any flat surface not parallel to the streets, adjust after the lights are mounted to get the most visibility out of your new light heads.
- DEDICATED - This is not a useless universal part, that never works quite right and leaves you frustrated. Our bracket is designed specifically for NFLH03 series light head, so you know it will work perfectly every time.
- 1-YEAR WARRANTY - We back all of our products, and that includes our brackets.
