Default Neo Wedge Bulbs in India?

i had opened my lancer dashboard, since most of illumination are not working, so i feel it is dull looking at nights, i have found 3 burnt bulbs .

1. cigar lighter
2. ash tray in dash
3. AC control

i got these bulbs from shop, since it is easily available, and common for most vehicles, but i found the hazard switch and fog lamp switch lights are also burnt, but the problem is it is so small, i could not source it from shops. I have removed the switches apart and circuits. i have the bulb in my hand, but i have to find new pair. to fix it. could anyone help me to source the bulb in india, it looks like

2pcs T3 T4 T5 Neo Wedge (Spark Blue) Dash LED Bulbs | eBay

the base may be different, but if i get the bulb alone or even with different base, i shall alter it with DIY. as i searched on google, it is called as "neo wedge bulb" which the negative and positive wires are twisted manually with the rubber base.

if not available, i have to manipulate smallest LED (as in mosquito bat) with resistor to do the job, any electronic student help me to do this. since i dont know the calcuation of resistor to get 12 v as input, i think LED willbe less voltage , around 2-3v. how can i overcome this? help please.

Use an SMD LED they are wired for 12 V. I have 1000s of SMD LED many colors(off white , red , blue and white) with me, From an earlier project. They work in a 12V car setup. PM me for details if interested. (2-3 mm thick)

Yes, me too done the same thing, as you said, got

3 nos of 3mm LED's of 3v,
5 nos of resistor to make it for 12v
2 nos of 5mm LED's blue color 3 v

All cost for Rs.8 (total cost)

I have removed on fused bulb from the switches and rubber base, and had matt finished the LED for scattered light, with the help of sand paper. fixed resistor to anode and it was easy, but the tough thing was to fit that into small place inside switch and in rubber base

could not bend LED legs easily on rubber base, so i broke it, and joined fuse wire, which can be easily bent and have done tough job to conceal the bulb in cramped switch, it took nearly 2 hours for an single switch, it was working fine, but the light was dim, I think, i should have gone for SMD LED's. Anyway, it is okay for now. and the hazard switch , i could not lighten it up, i think i have lost one small contact parts, which used for that bulb glowing purpose. If anyone has the picture inside hazard switch, please post it, so that i shall make one made myself, for that purpose.

Have Tried T5 LED for other control like ash tray, cigar lighter, but since the resistor is wide, it was cramped, so the contacts got shot and burnt the LED, But i am trying to use SMD LED in future,

.
If you are looking for those tiny bulbs, go to a Bajaj showroom and ask for neutral/high beam indicator bulb of the old pulsar with analog meters. That should work.

Let me check with bajaj showroom, for that 12v wire ended bulb, and thanks for the information. i too had that thought and asked about bulb inside the switch controls of latest pulsars, but two wheeler mechanic said, the bulb is not available seperately. so i dropped that idea, but as you said, i shall ask for instrument cluster bulb of old pulsar. Hope the best

pulsars bulb did not suit. and i have tried more shops, which deals in industrial electronics and even domestic electronics, but could not source 12v LED or 12v miniature neo wedge bulb.

But i think we can use chinese cheap decorative serial lights, which we use in decoration. It suits i think, but i did not buy it, it is cheaper. But i tried LED with resistor, it worked good, the only thing, i had spent nearly 3- 4 hours to install those LED into small switches, which lacked space. much tight space. But succeeded in doing those for 2 switches( hazard switch, and fog lamp). But i have another task for AC switch, but i dont know to remove AC control from the dash, since it is locked with blower controls.

I have also bought 5 LED (white) to place instead of dull yellow bulbs behind dash. but the LED power will be less, I could not source high power LED, though there is few, but it is big, will not fit into console. Let me try tomorrow for AC controls and update it.
