Just installed five 4" LEDs I bought off amazon and thought I'd provide some feedback on them. I installed two 30* spot lights on the center of the rack and two 60* floods on the out edges, along with one 60* flood on the rear of the rack. They cost about $25 a piece, so I wasn't expecting too much out of them, but I don't have the budget right now to spring for name brand lights at $150+ a piece. They are extremely solid feeling, have good mounting hardware, and put out a good amount of light. Way too bright to be legal to run on the street. All 5 of them seem to have more or less the same beam pattern so I think the spot/flood distinction is just something they made up. I left the rear light on accidentally for about 16 hours when camping last weekend and the battery showed no signs of being low, so they're good work lights. I'll eventually swap them all out for Rigids but for now they're a pretty solid substitution.

thank you for the review and link. if they get the job done, i'd be happy. I have busted and lost rigids...I go cheap now. $30- $50 a light is my new budget. I will buy cheap, even if it has a plastic guard in the shape of a chinese symbol, as long as it does its job.

 

They say cast Aluminum. Maybe scrap Aluminum from Fukushima, but hey, the price is not bad. And, as a bonus, they glow when turned off!

 

^ that would be a cool feature. I could get one of those hipster biohazard stickers

 

That's just like YOU Texans! Always trying to nuke people... yeah, I went there...

 

Yeee haw, succeed!!!

 

So, where did you run the wiring to hook up the power and the switches?

 

I'm using 3 relays, each of those has battery+ (With in-line 30amp fuse), load (to lights), ground, and switch (to inside the cab). The switches have the line coming from the relay, and a hot line coming from the positive terminal on the battery. I didn't want to deal with running a ground to the switch so the little LEDs don't light up, but other than that it all works well.

 

Very interesting. I've been thinking about replacing the factory spot lights on my truck because they suck.

These are so cheap I'm tempted.

Thanks for the info!

 

Ditto. I've got factory Yellows up front, and they really don't help much, even in fog. Very dim.
