If by inside lights you mean the dome lights( the lights that illuminate upon opening your door) then no no resistors that's just a plug and play type thing fairly simple to do. As far as exterior lights and especially the 2 plate lights I really recommend you keep those stock depending on where you live the cops will pull you over left and right and write tickets for that

I agree with the above post except for the bit about the license plate lights. I've converted my dome/map/license plate lights to LEDs with no problems. The only thing you need to worry about is the fact that the license plate bulbs actually run at just over 14v, not 12v. This means that they will quickly destroy any 12v LEDs you put back there. My suggestion, as you will find elsewhere, is to use a set from 42draftdesigns. They make the license plate bulbs that can handle the voltage.

I bought a set from SuperBrightLEDs.com and they lasted about 4 weeks. The set I bought from 42draftdesigns is going on 6 months with no problems at all.

There is also a thread somewhere that goes over the install. If you can find it, I added a bunch of pictures and a semi-walkthrough.

All LED's require resistors to run on 12v. However, most led retrofit bulbs have the resistor built in. If you plan on connecting raw LEDs, you'll need to add them yourself or you'll hear a nice fizzle and pop as the top of the led explodes. Lol

Also, the ENTIRE electrical system runs on 13.6-14.3 volts while running. If you only see 12v somewhere there is a problem. Fyi

Thanks for the direct quote!

Added a strip of LED's to the front since the 11 Focus didn't come with DRL's.

That looks clean!


Are your license plate lights still running well?

I also had the 42draftdesigns license plate bulbs. Mine have worked great for almost 2 years now. 1 of mine needs to be replaced but it is due to my bass firing toward the trunk before I sealed off my system. I can hit it and it comes on but I would rather not get pulled over for it being out sometime and me not knowing lol

Mine are brand new and sometimes I have to tap on it to? Is the bulb faulty? Or is it just not getting the right contact?

Make sure it is secured in the prongs and that the leds are facing down. The bulb is probably NOT faulty as they have solid products. In mine you can see where there are brownish yellow marks from the bass messing with the resistor lol
