I've always loved cars with leds. And wanted to install some kind of this staff on my car. I didn't want any chavvy tuning optics - I wanted just my standart optics with LEDs inside. And my dream came true - I ordered from US internet shop LEDs for all my rear lights and front turning lights. They are standart - you can just put them inside your car instead of flament bulbs. But that was not enough for me! I decided to delete the rear foglamps and one of parking ligts and connected all three lamps to one - stop+parking. That means that all three lamps work as parking lights and while breaking all three get brighter. It was rather hard to do - I've put some photos of how-to-do and the results of my work with comments below. Sorry for low quality of some photos!
That's how LED bulb looks:
One more problem I had - in front turning lights polarity was vice-versa (I wonder why) - no difference for flament bulb, but LED doesn't work! I had to open the headlamps, cut wires and solder it again, inversally.
Self-made connections in rear lamps:
How all the LED's look:
The computer didn't protest against LED's, despite their 4 times less consumption. But I still needed the load resistors because I deleted some connections.
They are very easy to install:
So, for results see the links:
