I appreciate the info, Steve!I bought these:
The Sealight HB3 type "S3 series" - I think someone on this forum has tried various lights, including the "S2 series" from Sealight and ended up using the "S3 series" I'm not sure, but I think the S2 series didn't have a great beam pattern, and Sealight does promote the S3 series as having a beam pattern that closely matches the normal halogen bulbs (just brighter and whiter). I can't say there is a consensus on which light is best, but I think I have seen more people who are happy with the Sealight S3 series than anything else (but that could just be herd mentality to some extent). I do think they are very good, but that doesn't mean they are the best option.
They are very bright & white, and the beam pattern looks very similar to stock. I did aim them lower slightly just because they are so bright that I want to avoid blinding other drivers, but they were a drop in replacement for the stock ones. Easy, no tools, everything fits inside the headlight housing.
See this thread for additional information (including a picture I posted with one stock and one Sealight series 3 lamp installed):
Cannot stress the importance of Headlight Aim in our Tellurides
Bridging many, many threats, complaints and issues we have all stressed. I have tested four different bulbs and given many Amazon's seller's good graces and the site's liberal return policies, i have been able to cycle through several of them. Right now i am on Sealight 3's which i thought were...tellurideforum.org
When you say you aimed them down, did you use the mechanism built within the housing to lower? If they are truly plug and play, what adjustments were done?
I was going to insert the new bulbs in the same orientation as the stock and hope for the best.
I really appreciate the time you took to write such a detailed response.If you look toward the end of the thread I linked to you will see a post from me last night (12/2) that includes a picture. The picture was taken after the left headlight was changed, but before any adjustments were made. If you look closely you can see pieces of blue painters tape on the garage door. They were placed so the bottom edge of the tape aligned with the top edge of the headlight pattern. (The tape was placed for the factory bulbs so I could have a reference to adjust to for the new lights)
it might be hard to judge from the picture, but the left light aligned “perfectly” with the two pieces of tape (from the original headlight). So from that standpoint, the LED lamps are about as good as I could expect in terms of beam aiming / height. The reason I decided to aim them slightly lower is because the bright central area is significantly brighter than stock, and I wanted to point it slightly lower to avoid oncoming drivers.
to aim the light lower there is a hex bolt head on the back side of the housing (I think it is below the cover where the lamp gets installed, but I’m not positive). I think it is a 12mm head. If you are going to aim your lights, I strongly recommend you do something similar to what I did with the tape on the garage door. Put up the tape, swap the bulbs, and make your adjustment without moving the car in between. (Otherwise it will be hard / impossible to get the car back in the same position).
Note that small adjustments can make a big difference, so take it easy. Mayb 1/4 turn on the screw. It’s probably a good idea to mark the bolt before adjusting it so you can return it to “stock” if you want to. (I wish I had done that)
Also note that aiming / adjusting the headlights on a garage door with the car so close is really not the right way to do this. I don’t know the procedure for a telluride, but generally the idea is to park the car on flat level ground, some distance from a wall (20 feet?) and then measure thetopnof the beam from the ground (where it hits the wall). Doing the adjustment with the appropriate distance makes it easier to get things right. Doing into. A garage door 5 feet away is not great...small height changes at 5 feet translate to much bigger changes 50 feet down the road.
good luck.
I'll give your method a try using the same bulbs and I'll return to post my impressions once the upgrade is complete.
