Hi Soni,

On behalf of BBS, the following link will tell you which capacity resistor to use

Current limiting Resistor calculator for leds

( i too learnt all this recently so )

[s0uljah]

Gotta love DIY!!! Even though these things are available its a nice feelng when you see the end result of of your efforts na

A tip for those working with LED's : To get rid of that spotlight type effect you can shave/sandpaper the head of the LED to make it flat. This reduces intensity a bit but gives a nice uniform glow instead.

Will post some pics when I get the time.

LED DIY are becoming popular !
Good one here, badboy

Are they affected by heat in the headlight assembly by any chance?
You can chose slightly higher resistor value to limit the current than optimal rating, just to increase the life of LEDs in that hostile location. Anyways, now you the know art of suffing more LEDs on to the holder, which will compensate to loss of brightness..

Thats a good DIY.

My only concern is with such bright parking light will there be an impact on headlight?

until now there is no adverse effect caused by the headlight heat. 470 ohms 1/4 watt (i ve used 1/2 watt) is the optimum rating, anything more prevents the LED from glowing.

No impact on headlight, infact the blue color is almost invisible when headlamps are turned on.

i couldnt get sleep so i went ahead with the speedometer blue lighting diy.moreover, night is the best time to check the illumination. so here goes :

Many thanks to souljah for giving the idea of flattening and sanding down the LEDs to get uniform glow.

Components:
6 5mm blue LEDs.
2 47Ohms 1/4 watt resistors.
plastic sheath of some wire (used as sleeves)
tape

tools:
soldering iron.
file & blade (used instead of sandpaper).
cutter.

3 LEDs filed until their gloss is lost:



The LEDs soldered in a series with the 47ohms resistor(at the +ve lead)


The LEDs temporarily taped to the speedometer unit to check the illumination and to adjust the angle of focus.


Behold, a blue speedometer.(just testing with one side alone)



@ Mods: Please change the thread's title to - "DIY - Blue LED parking lamp & speedometer lighting for Alto"

Waah Waah!!! Lookin Good!! I did something similar to my girlfriend's Dio recently.

@Ramie, How can i fit the LEDs into the usual 12V socket? it is the small socket i am talking about.

Finally, finished making another LED strip for the second lamp and tested:



Now i ll try to get some sleep.

that's a bling on man !!great DIY!

but as i know LED's and t he work i do with them ,led's emmit light in particular angles only
it can be 15 or 30 0r 60 degree ,by seeing your work i can say that it's a 45 one (just assumption) ,so the light in some areas will be a bright where in some areas will be decent .

I would suggest you to change the angle of led's (side ones a little bit towards outer point ) so that the spread of light will be much more ..

I hope you got my point

[eagle_f1]

AWESOME DIY job buddy.

Can it be done on the old ZEN ?????????

Please post step by step pics of the procedure.

[badboyscad]

Finished tweaking the angle of the LEDs and soldered them to the terminals.

LEDs soldered and insulated using tape:


End result:


Will post night shots tonight.

[shyamhegde]

Excellent effort and result ! You the DIY man now
I guess s0uljah's suggestion suited well for this application !

[sonirohit]

The Blue Backlit dials look really cool - it's high time you create a selectable color backlit DIY - have a selector knob connected to different colored LEDs, turn a knob and the backlight color changes. That would be the coolest DIY.

its already dark.. no pics yet!!!
