Does anybody know of a shift light that can be used on a diesel??

Cheers

um are you serious?? there is no real reason why you couldnt set one up but why

Yeah i need one, with the set up i am running.

How do you rig them up on a diesel motor? what is it going to run off?

shift lights i have seen have been part of a aftermarket tacho set up. Usually on the big pain in the arse 5inch monster tacho ones.

if the noise of a diesel revving its tits off doesnt tell you its time to change gears, something is wrong

Could try one like this.

Seems to require just a tacho input which your diesel should have anyway. Doesn't matter if it gets it from a dizzy, diesel pump or timing belt housing.


Shift lights are traditionally used to indicate a shift where the power (and thus acceleration) produced by the engine is the same before and after the shift. Can't think of an offroad situation where maximum acceleration is the most important thing...maybe sand drags - each to their own tho...

if you dont have a electric taco out put you can get one from your alternator

You should head out and watch the comps. I cant say that there is a stage where rev limiter is not hit.

I have one on my TD42 Patrol i used a Freqency Swich kit from Jaycar and a auto meter light.

I dose help when four wheel driving if you just put your foot down like me a light in you face dose help to back off or pick another gear...

Cool, cheers.

So the frequency switch kit allows you to adjust your shift light to you r tacho??

Is it pre made from jaycar or do you have to solder it together?

I have a Pivot brand shift light in my Subaru. It works off the frequency so is compatible with all motors. I have comfirmed that it works on a diesel.

and thats how i have the taco runing in my cruser and my rover

I cant see how people need a light to tell them that the car is going no faster...

What I meant is that shifting too early will cause the rev's to drop out of the ideal power range and shifting too late will mean optimum power is not being made before the shift.
In something like drag racing where winning/losing comes down to hundreths of second, getting optimum power to the ground is critical.

You're right, I haven't been to a 4WD competition. I just had the idea that in 4WD competition (maybe high speed stages excepted) it was more about getting to the finish rather than fractions of seconds.

Thanks for all the positive replys.

For the others, my question not for an opinion rather than where/how can it be done.

Cheers

Is it automatic?

Don't forget about the underbody flouro's and pair of subwoofers

Curious, what is the set up?

No manual.

The setup is a high reving diesel that i only want to rev to a certain rpm. As there is no power loss it is easy to get carried away.

Cheers

I don't know if your question is serious or not. But anyway, this kind of shift light is claimed to work well off the cigarette lighter socket.

I've never used one and don't know how reliable they are but they are meant to be able to calculate engine rpm by detecting the cyclical fluctuations in alternator output. You might want to research them a bit more before buying them as for all I know they suck.

So it's not an Auto...

So I guess the Getto blaster is up way too loud!

But seriously it should be easy to install a shift light, especially if the motor is controlled by an ECU as it already has a motor speed sensor - or even a Taco provided it's Electronic - Even Jaycar sell kits for it.

Now for the Fluro's I would go LED lights much safer for 4x4 driving, if doing this install a couple of camera's under side to you see the things you are hitting as you clearly will not be hearing them over the Techno.

was chasing something a bit more permanent than something for the cigarette lighter.

I dont hgave an ecu, it is mechanical.

Cheers

already got neon lights under the car......... Cameras tooo. even got a subwoofer next to each wheel.
you can also hum on my n#ts princess

Maybe the big tach could trigger off the cam sensor or off the alterantor.



Good luck Zac

Cheers,

not worried about the tacho as i have a VDO one already. Just want to wire up a shift light.

ive yet to see a diesel in a 4wd that doesnt start to redline at 4500, must be pretty hektik

Ok we are getting somewhere - oh and the gear you already have - Geez how the hell did I know you were going ti say that

Ok you have a Tacho - if it's Electronic what is used to give it a signal from the motor?
What ever it is will develop a pulse directly related to motor speed, this is what you need as an input - all you need now is a device that can be set to trigger a Big Ass Blue or Red Light when the speed gets to your desired motor speed.
Do you know what to use, can you solder?
