Upgrade suburban LT headlights to LTZ version headlights???

[eanthonyc71]

Has anyone done this? Is it plug and play or do you have to do lots of wiring to fit it..

why do you wanna do that???
ltz and lt s have different setups in terms of low beams. so you'll need something customized

Because LTZs have better headlights.

Very interested in seeing if these worked for you.

+1. Would be really interested in doing this as well if it is a fairly straight forward swap although I have a feeling it won't be.

The LT and LTZ have the same headlights. It's just the BCM is programed differently for the LTZ to have only the LEDs to be the only DRL while the LT uses both the low and strip. This is probably due to the LTZ having HID's and you wouldn't want them on for DRL's all day.

My buddy is a tech for GM and he's going to be trying to load up the LTZ light protocol into my LT BCM and see if we can get the DRL's to function as the LTZ's do.

they arent the same. they look the same from outside.
bulbs are different shapes plus the ballasts have fittings on ltz headlights.

The led strip is a completely different color on the LTZ. The LTZ has HID headlights, the LT does not.

so that means all I have to do is install the LTZ headlights into my suburban LT and that it
