If you have factory LED low beams you need an H9 for high beams.

that is a direct fit to my TB?

The Trailblazer uses H9 for high beams and H11 for low beams. I have Sealight LED's in my 2018 ZR2 and 2005 ZR2 and they are much better than the halogens. I already have factory LED low beams, but my highs are still halogens so I ordered the H9 yesterday.

I am confused. My low beams are the dull flushed out look. I am looking for the BRIGHT light.

Do you have factory LED low beams? There should be a Chevrolet LED logo inside the housing if they are.

ZR2Life did you need to remove or modify the housing for those at all or do they fit in the factory setup without issue.

These LED bulbs are actually more compact than the factory bulbs. I'm only installing the high beams since I have factory LED low beams, but there are several owners who have already installed both highs and lows without any issues and most importantly the dust covers still fit.

I should have my bulbs Monday and I'll post some pics.

Seems kinda weird they did LED for lows and fog, but then put in the nasty looking halogens for the Highs.

yes, it makes no sense at all especially since we paid for the upgrade.

I also just replaced the High beams on my RS with the Sealights and in the garage they seem to be good. I havent had a chance to try them at night yet.

What Sealight LED did you use for the high beams? My RS has factory LED low beams and the high beams are H9. It seems like some housings are using 9005 and some are H9?

Mine were H9's. I ended up buying these https://www.amazon.com/dp/B07JNY3ZVZ/ref=cm_sw_r_tw_dp_0HYXP0X9PRCDAT09AQJ7?_encoding=UTF8&psc=1 because i could still use the other set in my wife's car. But it was the H9's out of it that fit. I drove it last night and they look great.

Ok, from what I'm seeing you used the H11 low beams for high beams? I have the same H11 lows in 2 other vehicles, but the high beams like the 9005 and H9 use a higher wattage. Did you happen to compare the brightness between the halogens and the LED's you used?

I did a quick comparison in the garage when i installed them. But really gave them a test last night when I took my kids home. they live in a rural area where i could really test them out and i was quite pleased.

Ok thanks, I was curious if they were at least as bright as the halogens.
