Can anyone tell me if the tail lights off of an 03 Chev will work on an 03 GMC? I think I saw somewhere that they need a little modifying. I am sure someone has tried. I have a GMC and I think I like the Chevy Tail lights better.


Anyone interseted in swapping GMC tail lights for Chevy? http://dieselplace.com/forum/smileys/Cool.gif


Part # and price by chance?

<DIV>You can put the Chev lights on a GMC or an older Chev, but you have to get the wiring harness for the new lights also. My neighbor did this to his 2002 chev. He got the lights &amp; harness from JPCustoms.</DIV>

Thanks, I don't know why I didn't check there in the first place.

I swapped them on my 03 GMC and they look much better. You can see the before and after in my pics in the sig. If you get them with the harness it is a 5 min swap. Mine did not have the harness but it is very easy to make them work.


Went to AutoZone and picked up two replacement liscense plate light sockets that hold the 194 bulbs and a couple bulbs. Spent about $10 total. Removed the GMC lights and located the "lights on" hot wire and used a quick connector to splice the new socket in. Did the same for the ground wire. Now I had the 4th light. Trimmed two of the tabs off the socket and popped it in the Chevy light. The stock GMC light sockets need to me rotated slightly to fit in. I had to trim a couple of the socket openings on the lights so the tabs would fit but very minimal. Took about 10 min on the 1st and less than 5 on the second. There is no cutting wires and the install is very quick and easy. Definately make the swap!

I like the safety of the amber turn lites, it seems to draw more attention then the flashing red lite at nite when the running lites are on.


When driving semis for years I saw a lot of difference between the amber turns and the red turns on the trailers and how much faster they are noticed.

I would be interested in swapping my Chevy lights for GMC lights if anyone is interested within reasonable distance.....

I'd sure be interested. Mine look like new and are 6 months old. The problem is we are a long way apart and probably neither of us want to do without during shipping http://www.dieselplace.com/forum/smileys/Cry.gif

Exactly. And the shipping fee to boot http://dieselplace.com/forum/smileys/Cry.gif

I put the Chevy lights on my GMC and the lights came with the wiring tail attached.

If you're swapping chev to gmc and visa versa are the harnesses from the tailights down to the connection box interchangable- in other words do they both plug in on the block under the box in the same locations and everything works as it should? I know the harnesses themselves are different due to the side marker lamps on the chev lights.

I agree.

The new Chevy tail lights are terrible as far as visibility to other drivers goes. Yeah they look cool, but when the brakes are on and the blinker is flashing, it's very difficult for following drivers to see in certain situations.

My brother has a 2003 Chevy & he is looking into switching to the amber signals.

Not bashing the lights, but I do notice a safety issue whenever I follow my brother in the dark.

My pics show the plugs on the GMC and the tails of the Chevy....http://www.picturetrail.com/gallery/view?p=999&gid=1267240&uid=147085

There is also a pic of the truck at night with one GMC and one Chevy tail lamp lens installed. The pic does not really show the true brightness of the two round lamps below that contain 39 LEDs each.Edited by: TxDoc

I see the pics but still haven't heard an answer to the question. Anyone done this?http://www.dieselplace.com/forum/smileys/Question.gif

Mine plugged in directly. No splicing, no extra pigs, just unplugging and pluggin back in. Mine came with the tails. When poeple first did this, one or two folks made posts about their Chev lights did not come with tails attached. Not sure why. Mine did.

Thanks txdoc- I want to swap mine to the chevy ones that a friend has on a work truck and vicy versa. Now we know it's worth the effort to unclip the harnesses and swap.http://www.dieselplace.com/forum/smileys/Clap.gif
