Do you use some of these lights http://www.ledshoponline.com/automotive_leds.htm

8 LED bulbs make up this light

These LED replacement bulbs fit readily in every 15s series single pin bayonet fitting found in most applications for 12V automotive lighting

LED lights uses 80% less power than incandescent bulbs

LED lights are unbreakable

LED lights never fade

No we don't. Appear to be more trouble than they are worth, don't perform like standard bulbs and are not suitable for some skodas due to the way they control voltage to lamps for stop/tail functions etc.

tried these in mine they were hopeless,caused a warning light to flash on dash and not very bright either.At service they had to change the brake switch as it showed a fault! Tried LED side lights as well these melted and i couldnt get them out!

These draw very little current so the computer sometimes thinks there's a lamp out and brings up a dashboard warning. You need a resistor to increase the load and fool the computer. These lamps are getting better all the time but can't yet compete with the equivalent filament lamp. Some Skodas use duty cycling to control lamp brightness. This means you might only need 1 filament for a stop/tail lamp. Duty cycling effectively reduces the mean voltage at the lamp and reduces its output for tail lighting function and gives full voltage for brake lamp function. LED tail lights are not compatible with this and will give poor performance if any. Melting LED sidelights seem to be a problem. Modern headlights are very well sealed and the heat generated by the dipped and main beams is substantial. I plan to put filament daylight lamps in for my sidelights (which are white with a blue tinge). I want to put LED lights into my front fogs though because I never use foglights anyway and I think it will look the part. I'm thinking of these

(subject to a conversion to accomodate the lamp in the lamp holder).

I've bought LEDs from there before and they are usually good, although a couple of the bulbs have failed. I have their LEDs in all three of the interior lights in the front, plus the number plate bulbs in the back. Those seem not to last which suggests to me they aren't up to the task of withstanding my subwoofer's bass vibrations...
