My $0.02 . . .
I redid all the lenses on my truck a few years ago in a rewire. When I did I ran LEDs everywhere except the headlights . . . and I didn't like em. Spend your money elsewhere, I didn't use that kit, but I pieced together a similar kit for about $90.00 and sold it for the same. The thing about LEDs is that they are directional, from dead on they are brighter, but from slight angle they loose their intensity, my thought driving a classic in SoCal I need every ounce of brightness to keep the idiot on their cell phone from rear ending me. Also the lenses on our rigs were never designed for these lights so the grooves in the plastic that reflect the multiple angles from a normal incandescent bulb actually make them brighter in a side by side comparison. So if you want brighter lights replace your lenses if fogged, repaint (or chrome) the reflectors, make sure you have good grounds and replace with quality incandescent bulbs. Plus you can wire your side markers to flash with your turn signals for added blinky blinky depending on year.
