Review on 🏎️ Painless Performance 80111: Superior Replacement Diode Assembly for Race Car Switch Panels by James Wonsley

Worked great. When I switched to secondary headlight lenses in my f350, they separated the high and low beams. When you turn on the high beam, the truck will stop powering the low beam cable. I placed this diode in the high to low beam line so that when the low frequencies are on it doesn't provide current for the high frequencies, but when I turn on the high frequencies it maintains the low frequencies. Great connections, well made product, with 4 tabs, 2 for the hotline and 2 for the line that gets you hot.
