what varun says is perfectly correct. newer plastic reflectors are not good when used with high wattage bulbs.
As far as LEDs are concerned, the power consumption is very low.
with SMDs as low as 0.5 W while a normal T10 bulb consumes 5W (4.5 W difference) so you can assume how much power is saved.
i am using LED as given below
1. 2 X Parking lamp
2. 2 X side indicators
3. 2 X number plate
4. 4 X high mount stop lamp
5. 1 X cabin lamp (front)
6. 1 X cabin lamp (rear)
so using 12 SMD LED bulbs (total 6 w instead of 60W, not that we use all of them at one time)
1. led used for cabin light (this one is low on the light output)
2. gives much light but after some time turns to blue (may be my bad unit)
3. single SMD, gives good light with the front lens
4. same as above gives blue light (i used this to get Blue eyed boy effect later removed as advised by FJ CRUZER
, as night visibility is poor.
5. 4 smd gives good light
6. single 5050 SMD led without lens
, medium light (but one of mine fused on the long run)
7. a DIY interior lamp made from 2 units, got another so not using it
8. T10 wedge lamp 5 w OE
9 OE cabin lamp
Please note that LED uses different technology so that heat generated is less and it gives a long life time ~50000 hrs.
All the above LEDs are spares. right now in my office Audit is going on so i have brought files to home and working on it. (logged on to TAI
, once this is over i will take photos of the bulbs in my car and then post in my ownership thread, i haven't updated it for a while)
I have only done T10 LEDs till date, now planning to purchase the twisting type and replace indicator, reverse, tail lamp, fog lamp etc.
Also LEDs come in various color temperatures
pure white gives the CFL like color (cool daylight)
warm white gives you the incandescent bulb like feel (my rear cabin light is this)
a cabin light replacement
if you are purchasing cabin light led, please measure the distance between the points, for me the front light was 31mm and rear light was 36 mm
purchased this LED to fit in the car, but waiting for a suitable place inside the car. this is a high power 3 W led 12V and with lens so that the light is focused.
As for the headlights, i used Philips Extreme Vision bulbs, Xenon (normal halogen bulbs use other gases). i have taken snaps with and without the Extreme vision, once my audit is over i will post in the ownership thread. don't expect miracles, (i did not go for 100/90 basically because of what Varun said, and i didn't wanted to mess up with the electrical. as for HID my uncle who is DMVI is strictly against it
he won't let me do any mods, i have installed the IceCool Shield without telling him. he had me rip off my sunfilm (lightest green and looked like OE tinit). now i have to install 70VLT garware next week as the heat is too much on sunny days. and planning to use nail polish remover as Lucas
suggested to hide the printing).

A normal LED has a driver voltage of ~3.6V, our car's electrical is 12V. so to reduce the voltage the manufacturers use either a resistor (with single SMDs) or use multiple LEDs in series (or both). the power rating varies we have LEDs ranging from .25W to 30W (out door use only) these high power LEDs require proper heat sink.
