Review on Xotic Tech 4-Pole 12V Push Button Switch with LED Indicator Lights for Toyota Camry Corolla - Fog Lights, DRL, LED Light Bar, etc (Size: 22.8 x 22.5 mm) by Greg Muin

I may have missed something in the instructions but I blew a fuse when connecting to existing wiring. I haven't seen the conversion instructions. I'm not even sure if my lightbar is compatible with this switch. I've tried repeating it myself, but to no avail. When power was applied to one of the wires, only the blue light on the switch lit up. I thought the light would be controlled and I live without blue light but... I'm sure it would be easier for a pro. Don't come with bundled light bar. You don't need to go elsewhere to research this, but maybe it's common knowledge so no instructions needed?
