Hey guys I am soon going to be replacing all the old light bulbs in my car with LED, but now the question arises... where do I get them from? I have done some searching here and two places have come up. One is Classic Industries. The other is Super Bright LEDS.com. which bulbs should I get? There is so many to pick from and I don't really know which to get. The interior and dash/instrument bulbs seem like easy choices, but tail, parking and turn signal lights have many choices. Also can I replace my fog lights and head lights with LED's?

 

I have used SuperBright LEDs for my dashboard and marker lights. Now, keep in mind I mostly drive during the day, and once a week at most; a few of those dashboard lights have failed. Trying another bulb in the same location works, so it's not the circuit "board".

Another thing to keep in mind is that unless you get bulbs that spread the light, LEDs are directional, your dashboard will have hotspots and areas that will barely light up. Same for the marker lights.

 

Some advice from my own experience for you:
I bought some tinted side marker lenses and wanted to use yellow LEDs for the light's color to be more true to the original when the lights are on.
Nice move, but the circuits use reversed polarity on the side marker sockets when you have the lights on and want to use the turn signals.
So either you'll have turn signals when the lights are switched off and no parking light when they're switched on, or parking light but no turn signal function.
So you will need to dive deeper into the electronics if you want to use LEDs there.
