Low beam problems on SRX 2012 - successful replacement assembly?

I am one of those lucky SRX owners (2012 - purchased new) which now has failing low-beam lights. Has anyone replaced the headlight assembly successfully by using replacement parts online? I don't want to pay the dealership to replace with the same defective parts. Thanks in advance!

While our 2012 headlights are fine (one leaks a smidgen since I resealed it a few years back) and I have upgraded them to HID's. I will say that my buddy who works for a auto repair place says that the aftermarket ones are the only thing they install. He says that they work just fine. I've seen those headlight for $250 each and there was one place that was even on sale for $250 for two. Do some google searches for them. They can be had cheaper now that the cars are getting older.

Hi,

I posted a detailed replacement procedure post a few months back (Mod edit: https://www.cadillacforums.com/thre...-srx-luxury-halogen-to-led-conversion-along-with-headlight-replacement.1057353/). I replaced the headlight assemblies and installed LED lowbeam lights. It has improved night visibility greatly.

I'm in the same boat. I tried the LED lights and they were awful. I installed an HID conversion kit from Diode Dynamics and they helped but I think the projectors are now failing. The driver's side light is now reduced down to the right half of the beam and the other is getting dimmer by the day. No moisture in either. I found the Anzo aftermarket assemblies that claim to be brighter than the OEM assemblies but I can't find many reviews on them. I'm confused as to buy the cheaper $150 aftermarket or the $300 that "claims" to be brighter.

I have a 2014 SRX Luxury and the low beams a dangerously dim and totally useless, my wife refuses to drive this vehicle at night. After a lot of resort it looks like the issue is not with the bulbs but is with the assembly itself with the reflective mirror not reflecting the light forward. Has anyone replaced the entire headlight assembly with aftermarket assemblies? if so what brand and did it work? I can't believe that Cadillac has not recalled this ongoing dangerous issue ones and for all, peoples lives are at stake. This is the largest complaint about the SRX Base and Luxury cars and it is time that they send out a technical bulletin and get this fixed.

OK, I had terrible low beams on my 2013 SRX, I did get a letter from Cadillac that they would reimburse me. So I went out and bought these after market headlights, and also upgraded to the Dynamic Diodes HID and must say my low beam are now amazing. It did take alittle work,as these after market lights have 4 adjustment screws and are not easy to get to. So I ended up taking the bumper off again and waited till dark and removed the headlights and kept fine tuning the adjustments .They are so bright that I am getting lots of people giving me the high beam, as they thing I still have my high beams on.

I have a 2013 SRX and had this problem develop slowly, and I did solve it by having the headlight assemblies replaced. But my trek to get there is perhaps worth sharing: I know that on old cars, dim headlights often result from corroded ground. It's an electrical light, after all: it has to be on the supply side (not enough current, probably amps not volts) or on the ground side. First I tried simply replacing the original bulbs with new bulbs, ostensibly brighter than the original. If anything, the lights were even dimmer with the new bulbs (and certainly were no brighter.) This eliminated anything to do with the bulb itself as the problem, no matter whether it was ground-side or supply-side. I put the old bulbs back in, and started experimenting. I rigged up a way to run a separate ground to the drivers side light (which is much easier to access), by running a wire from the chassis into the plug along with the bulb, and I didn't see any difference. So I figured it was on the supply side, and I suspected that the circuit that controlled the daylight running light mode was perhaps degrading over time, resulting in fewer amps coming to the bulb. (I think the daylight mode is created by reducing the amps that come to the bulb, and that the voltage remain constant.) I determined that the low beam lights, though not bright enough, were still a lot brighter that the daylight running mode. (I did this by pulling into and out of my garage, and seeing the lights get noticeably brighter and dimmer, as seen in a mirror I placed directly in front of the car). So I thought I'd rig up another supply path straight from the battery to see if the bulbs were brighter if I could set and hold the amps constant. Before I could get this rigged up, I did something (inadvertently) that caused a relay to fail (open) somewhere in the headlight circuit for the driver's side only. So that low beam light was out altogether, whereas the passenger side light had not been altered. This was really dangerous, as that one light alone was nowhere near bright enough to drive. So I had the dealer find the problem: the technician detected the open relay. I had them replace that drivers side headlight assembly only. The result was that the drivers side light was back to its normal, "new" brightness, and it was OK to drive that way. The drivers side light was much brighter than the passenger side light. After a few months, I had the dealer replace the passenger side headlight assembly as well, and now they both look like new.

I'm dealing with the same issue. Do you know which relay it was?

When will Cadillac recall the headlights on the 2013 SRX. It is so dangerous. I cannot see anything unless I have my brights on which endangers other drivers. Please recall the headlights! How can they get recalled in California because of a lawsuit but nowhere else. Is it darker in Cali?! Please help!!

Folks, help me out here. I too have dim headlight low beams in a 2012 Luxury model. Is the prevailing issue fogged or less than clear round lenses that the light comes through? Mine look a bit hazed, but just a bit, although I can't say I know what new ones look like. It sounds like just replacing the bulbs is worthless, but also that it has been adequate for some. Are these lenses not cleanable/polishable from the inside once the headlight assemblies are removed? And I'm talking about the 3" or so round lenses near the top of the cluster, not the big exterior cover that covers all the lights. Mine appear to be dry inside.

Our daughter purchased a used 2012 so y'all might be interested in this. The talk about LED/HID lights is great. Her car, unbeknownst to us, had this done. Unfortunately, she is now failing inspection because VA changed the law such that if your car didn't come off the line with HID you can't have them. Now I have to get with the dealer from which we purchased to understand how it "passed" inspection prior to purchase. It's always somethin'!!

good to know but hers is the Luxury trim. I'll be talking with the dealership Monday since it seems that they sold us an "illegal" vehicle. It should not have passed their presale inspection so this will be an interesting conversation.
