I recently customised my headlights with a full blackout housing and used the 90mm halo switchbacks around the lightbulb housing. The quality of the light out of the box was great and had everything i needed to wire things together. When using the light, the white 'DRL' is super bright and crisp and the orange blinker switchback is just as great. There is a 3 second delay between blinker switching off and white light coming back on but its a great function and really sets off the car. Thanks iilumo
Switch back drls
I've done heap of headlight work and these are by far the best lights to use in regards to brightness and uniformity of the lights. Top quality item and will continue to use.
