LEDs in headlights

I recently just modified a set of fog lights to light up blue when active. Eventually they will indicate if my remote-starter has been activated (but they can still be switched).

If you don't mind doing a little drilling into the headlight casings, i would do the following:

1. Search online for LED and RESISTOR packages. The greater the lumens or candela, the brighter the LED. Becarefull, if you only  want to light them up slightly, you will either want more lower candela, or less greater candels LED's, my recommendation is go with a few brighter bulbs.

2. Tap a dent into the metal case with a screw driver, as to indicate where you want the LED to go. Most people hide them among the rims or behind the light itself if you have such a set up. I recommend putting them somewhere unobtrusive, and towards the grille of the car (so that the bulb points away from the grille). The dent also helps your drill bit from floating around and moving when you go to make the hole.

3. Put the LED in from the inside of the housing outwards, if your housings are sealred, do the exact opposite. Hot glue the led in place, making sure that the metal contacts of the LED are not touching the metal housing, as this will ground out the LED

4. solder on a resistor, run your wires to whatever switch you want, and roll.

NOTE: if you want to test LED's, i recommend just touching them to a 9 volt battery, the current will usualy not burn the LED out, and its a good way to see how it will look before you finish fabrication

actually a 9volt battery can easily burn out an led.. or at the very least discolor them. best thing to use is one of the watch cell batteries that most stereo remotes use. they are 3volt, which is what most leds are rated at.

just lookin out..

I did this mod last year and love it still. I did a write up on the Santa Fe Forum and on my show team's board. Here's the link, http://p211.ezboard.com/fhyundaisantafemessageboardfrm52.showMessage?topicID=749.topic and a shot of the result

I just bought some LED's and resistors off of ebay (by the hundred for about $12).

sorry, forgot to mention that they are wired directly into the 12volt source with a toggle switch in the center console.
