changing to LED

I'm wanting to change my 72 chevelle gauge cluster bulbs (fuel, speedo, tach) to LED bulbs. I have the dash pad off. How can I tell what to unplug in back of the cluster. I have round gauges by the way. Thanks for any help

Re: changing to LED

I got some LEDs off eBay and simply changed them. Unless you have a one wire Altanator though I think you would have to leave that a regular bulb.

Re: changing to LED

I just got 20 bayonet type blue LED from E-bay really cheap for my instrument panel . They are very bright. I measured the current on a LED Vs a Filament type bulb, I was surprised how little it draws. The LED produce only 30 milliamps and the filament produce almost 300 milliamps! This mean it will require 10 LED bulb to one filament type bulb. That will reduce wear on the headlight dimmer and extend battery life. It is worth it.

Re: changing to LED

Are these bulbs directly behind each gauge?

Re: changing to LED

Nice bulbs Louis but they won't fit my socket. The bulb base including the bulb is all glass

Re: changing to LED

I install lots of incandescent, low voltage lighting in homes and businesses where looks are important. The reason it is so popular is because of the warm light it gives off. I was told it has the most colors of the spectrum... LEDs leave a lot to be desired unless a white, utilitarian look is desired, like a apartment hallway, closet or the local garage...

Might want to rethink swapping the incandescent lights. My customers pay me big bucks to install it in there homes...

I have my 69 El Caminos dash apart now.. I'm looking for a couple boxes of Made in the USA Westinghouse or GE bulbs..
