Alright, my review of Spyder LED tail lights....
They're badass, looks so much better than stock and work right out of the box even with LED front signals which I didn't expect! They're just as dark as my stock tails with the 50% light smoke headlight armor so I'm happy about that. One thing I don't care for is the clear lense over the reverse lights.... It was black on stock tails but this one is clear. Pretty sure a little tracing and I can cut out some vinyl that'll cover the sides up.
At night they're awesome, the sides light up more than stock and just look cool. Down side is when using brake lights or signal there isn't a huge difference in light output. it's enough I"m not worried about someone running into me, especially with stock 3rd brake light but not as much as I'd like. As you can see in pictures, the stock LED running lights on bed are brighter than tails, but when braking or signal the tails light up about as bright as them. I hope that explains it good.
Overall, by all means GREAT upgrade! I'd do it again in a heartbeat!!!!
