So since I'm not made of money. When I was looking for LED Taillights. I came across this site, which had them cheaper than I ever seen. http://www.360tuners.com/04-07fordf150ledtaillights-pairblack.aspx I now have had these for probably near 90 days now. They are bright has hell. I haven't had any issues with the turn signals blinking faster either. They are pretty solid in my book, and I wouldn't hesitate to order from there again.
They have a built in resistor that compensates for the LED hence why you have no blinker issue. For the price, those are nice. Especially if you aren't wanting to drop $300 on some Hella's (I'm guilty). My only issue w/ these are the RED Circle on the bottom... but that doesn't bother some so hey, I can't complain. Take a pic of your truck rearend to show them off to everyone.
see, those look better on the truck then just an "image" of them. looks real good in fact, better than expected.
