Changing dash lights to LED - The 1947 - Present Chevrolet & GMC Truck Message Board Network

piecesparts · 03-05-2013, 06:26 AM

I know that this has been discussed before, but I thought it would be good to go at it again. I have an 84 GMC that the dash lights are dim and I want to upgrade. I am really not wanting to tear the whole instrument panel out to paint it or replace it, so has anyone just replaced the dash bulbs with LEDs and what did you think afterwards. This truck is not driven daily, but there are times that we do travel at night.

This might help http://www.73-87.com/7387garage/interior/dashlights.htm The last car i did the swap on was night and day,Before you couldn't read any gauge now you can read them all in the dark.

white

I think if you put led's in there that you may not be able to dim them.

Project77 · 03-05-2013, 10:08 AM

where do you buy these led's for the dash light?

mrolds88 · 03-05-2013, 10:19 AM

Just do a search for 194 led. Plenty of results

Project77 · 03-05-2013, 10:23 AM

how many total bulbs does it take?

wyattglock · 03-05-2013, 10:31 AM

When I replaced all the bulbs in my 2wd, it took 11 bulbs. The 4wd should take 12.

Project77 · 03-05-2013, 10:37 AM

thank you

Project77 · 03-05-2013, 10:44 AM

I've done it, and loved it. Got mine at superbrightleds.com.

And yes, you can dim LEDs.

Buy the color spectrum you'll see. White for the instrument panel, green for the turn signals, amber for the caution lights.

**rs74** · 03-05-2013, 11:04 AM

What can you use to change the color of the turn signals. Years ago I used some red construction paper and replaced the green to have red turn signal lights in the dash. I am thinking blue with my build.

Get blue spectrum LEDs.

INSIDIOUS '86 · 03-05-2013, 12:34 PM

I never needed LEDs I just painted the backing white and the cluster white and put in red bulbs. The red bulbs are still brighter than originals

white paint makes the world of difference
I added a second set of red LEDs to work independant from the stock whites

Low87 · 03-05-2013, 12:55 PM

I put chrome foil tape over the blue plastic. While I was in there I swapped the dead/dying bulbs with LEDs. Lower draw and longer life. Might as well.

DO NOT buy the brightest green LED for the turn signal indicators. At night my cab lights up like a disco and I go half blind.

I changed my dash lites to the 17177's and the are plenty bright.$9.25 for 10. but try your local RV store for 168 or 194's I give around $4.00 for a box of 10.

JellyBeanDriver · 03-07-2013, 02:33 AM

I used ones similar to these from
Ebay

Changed them all out of the cluster except for one (ran out). Dims fine I think because of the one incandescent I left plus the other incandescent in the heater controls acting as a good enough load for the dimmer rheostat.
