Hello everyone:

I had some refreshments done to 2003 F-150 5.4L 4x4 (chromed the rims, repainted the plastic, repainted the fenders and grill) and I talked to the guy at the shop and he said I wouldn't be able to switch to LEDs because the electrical system on my truck wouldn't be able to handle it. I can't remember exactly why he said I couldn't do it. Is this true? I was really looking forward to getting the LED lights, LED Fog Lights, and Raptor style lights from F-150 LEDs.

Thanks!

Edit: I checked the wattage that my truck can handle and I am able to do LEDs. I will be doing LED lights, LED Fog Lights, and Raptor style lights from F-150 LEDs.

Not true. Turn signals just need a resistor or a different flasher designed to work with the reduced resistance. I have front turn/park LEDs with the flasher and they work perfectly. Search my headlight thread for the flasher name. Any other bulb probably just needs to be verified that the wire/fuse can handle the amperage, but may also need resistors (not sure).

Have you driven around lately? Everybody and their momma is running around with all kinds of LED bulbs. Stop talking to that guy. He doesn't know what he is talking about, Willis.

Yah. Everyone also revs there engine while it is cold. Just because they have it doesn't mean it is good for it.

Thanks for the information! Will check it out.

I put a LED light in my motorcycle because it has a wimpy alternator output. They've come a long way in the bulb designs. However, I will say this, I aimed the headlight down because they are God awful bright. The bulbs and reflectors are designed as a unit, lots of guys put the bulbs in, not knowing, or maybe caring that they are blinding people. It's stupid and rude to do that, and illegal btw, so please make sure you adjust the beam if the bulb does not match the OEM design.

I will keep that in mind. Thanks!

Real answer.....vehicles are approved by DOT for on road use with the OEM headlamp specified. Anything else ....is not technically legal. All bulbs of a given designation have a lumen range that they have to be within because of this. This is why you can get replacement bulbs that may appear whiter, but they really don't have more light. For instance, there is a legal limit to what an H7 can have for lumens due to this.

Yes these lights ARE DOT approved.

Check your states vehicle laws before converting as there are a few states that do not allow headlight conversion and will not pass state inspections if it does not have what it came with.
