This is my another DIY. Neutral light for Maruti 800 using simple light detector circuit.

Things needed:

LDR: 6 Rs.
BC547: 1.50 Rs.
1K: 1 Rs.
Laser: 25 Rs.
Led holder: 1 Rs.
10K POT: 5Rs.
IN4007: 1 Rs.
Screw Clip: 10 RS.

The transistor is used as a comparator, which compares the preset resistance level and the LDR resistance level with reference to ground. Light falling over the LDR from the Laser instantly lowers its resistance and allows more current to flow to the base of the transistor.
Which in turns the transistor conducts and activates the Neutral light.

Hey SPELLBOUND, superb DIY. When you have done so much why don't you go ahead do this for all gears so that it will show as gear shift indicator. That will take this DIY miles ahead. All the best.[:D]

Hi SPELLBOUND,
Fantastic thought and implementation.
Would an IR or Hall sensor work equally efficient for this application?
And please include a write up on how the "N" symbol was brought into the instrument cluster.
Thank you.
Hai Ilangop,
You can use Hall effect sensor for this DIY. The "N" symbol was marked by using Stencil and compass.

Hai Varun,

Here is the simple circuit for gear shift indicator

Wow, Nice DIY, but I am not sure I can do this. I don't know these things. Your DIYs are super![clap]

I just take it from a damaged mahindra xylo instrument cluster and stick it over there. You can draw the same with a compass
