I finally finished it.. after procrastinating for 2 weeks... hehehe..

after countless times looking for the right materials..
after 6 hyper white LEDS
after 2 50 OHM resistors which was later scrapped and replaced with 2 150OHM resistors
after 8 pcs of pin connectors
after soldering the pieces together...
finally did it.

i'm quite happy with the results... though i think i still have to re-adjust the focus of the LEDS to fully light up the dash...

the only problem is.. now it doesnt match my lights up front.. eheh. dunno maybe its just me being OC...i think i need to buy me some hyper white H4 bulbs...

Nice LED project. I'm thinking of doing the same to my SDL since some of the window switches and dash lights are burned out. I'm really not looking forward to ripping everything apart though.

Wow shes bright. You can even read the odometer without turning on the cabin lights.

That is great. Mine are really not very good.

Is there any chance of a wiring diagram as to how you put it all together? Wiring is not my strong point. But I can read and follow directions!!!!

Thanks,

Stephen

I agree with Stephen. Directions for the electrically challenged. Looks excellent, by the way. I see somebody else out there doesn't have a tach.

Why is it necessary to use a resistor? are the leds that delicate?

I put a red multi LED light in my boat last year I just wired it normally into the 12v system, (maybe it had a resistor built into the plastic case?)

thanks,
Robert


Ps. Looks great BTW! In my jeep I use a flashlight to peer at the last 2 working gauges.

See Brandon314159's post earlier. One selects an appropriate resistance to get the desired current flow for the LED. As he points out, too much current will damage them.
