Shift-light installation

Hey,

I want to install only a shift light. Is it possible to use any bulb/LED? Can someone tell me how to actuate the light at the desired shift point?

Thanks

There are dedicated shift lights from autometer. You get a programmer and remote/input to set the shift point.

If you meant locally, I'm afraid there aren't many home-made kits out there. One way to do it would be to install a bulb in the dash, and take a spliced input from the ECM such that the bulb lights up when you hit the rev-limiter. Two disadvantages, though.

A) You can't change the shift point, and
B) You're messing up the OEM harness-for the sake of experimentation that MAY or MAY NOT work.

Here's the link to the Autometer shift light section...

May actually need a physical feathertouch switch on the needle, methinks.

Don't the meters work off increased current flow? If so, one should be able to use a bulb or LED that lights up only with a particular current rating.

Ok, update... Auto Meter sells just a shift light with "pills". They appear to be some sort of resistors which do something so that the thing lights up at the desired rpm. So if you want 10,000 rpm, you put a 10,000 rpm pill into the standalone shift light.

Any ideas on how to implement this?

Ok, I have figured out how to do a DIY thingy for this. Works reasonably well. I tried setting up 7800 rpm limit. When I hit that limit some 10 bright blue LEDs start flashing.

Congrats Harrie. Looks like you are putting your classes on Embedded systems to good use.

Does the shift-point stay same for all gears? stupid question, I know, but is there a way we can control the shifting point for each gear so we get the optimum shift point for all gears.

The shift point can be set as needed. Working on that still. As of now it can be changed only when the car is switched off.

Let me see about the gears part. But why do you need separate shifting points? I shift at 8000 rpm in all the gears

What's the point of fitting a shift light?

You can always decide when to shift from RPM.

Or I'm missing something?

When you are driving very fast and shifting at the red line you cant afford to take your eyes off the road or hit the rev limiter.

Some people shift exactly at the red line by listening to the engine note, but I prefer having a visual prompt telling me when to shift.

Do you get the autometer shift lights in our accerories shops? is it popular.

Its very useful to have a shift light when u r draggin or out on the track. The shift light should ideally light up a few hundred rpms before the limiter. So with your reaction time counted in you are shifting just below the limiter.

Excellent idea v1p3r! I too would love to have *only* a shift light, for a pre-decided upshift point. Would look great...subtle yet serving the purpose.

Will watch this thread closely.
