I'd like to get some LED lights for the rear tailights and 3rd brake light on my truck.

I know there's a bunch of different brands out there, which brand do you all feel is good?

Edit: I've read somewhere that after one puts LED lights on there F150's, the radio stops working or the turn signals don't work right?

 

LEDs have a very low current (amperage) draw. The bi metal turn signal flashers require a certain amperage draw to heat the switch up. Once the switch reaches a certain temperature, the switch opens up and disconnects power from the light. LEDs don't heat the flasher enough to trip it. Newer vehicles are getting electronic flashers, so this is becoming less of an issue. However, if you have a metal flasher, you will need to change to an electronic.

I don't think the tail light circuits will have any bearing on the radio, unless the 05+ CAN is more integrated than I give it credit for.

 

Before you buy, ask if the units have built-in resistors (the ones I bought from XtraLights do).

Here is a old thread with a lot of good information, pics, and videos or LED lights.

I bought new tail lights instead of just the bulbs. They were not that expensive and I like to look of the new lenses. I bought red/smoke lenses.

take a look

I fabbed some separate LEDs into the OEM taillights that I like the look and just replaced the bulbs in my third brake light w/LEDs from superbrightleds.com

 

you dont need the resistors, you need to buy the heavy duty flasher unit

 

Just because it's heavy duty doesn't mean it will work with LEDs - you need either an electronic flasher or resistors to keep the flash rate normal.

i installed front LED signals and LED tail lights, put an EP-27 Flasher Unit in it and it cured all the flash rate problems

 

The EP-27 is an electronic. The terminology difference is, the old bi-metal flashers came in standard and heavy duty. The heavy duty was pretty much required for any tow vehicle because hooking a trailer increased the load on the circuit and caused the lights to flash too quickly. The HD flashers took longer to warm up and kick out. Electronic flashers use a time based rather than current based sense. You can get fancy ones that allow you to adjust the time off and time on, or the generic like the ones used on heavy trucks.

 

If you're buying LED light assemblies that have resistors installed (not all do), then the flasher type doesn't matter; that's why it's a good idea to ask before you plunk down your $$$.
