Typically the LED chips face on the sides (Left & Right). Make sure you get a set of bulbs with resistors. Usually they are built with the bulb, so all you have to is plug it in and you should be all set. You may have to adjust the beam.Hello all. I’ve been wanting install LED bulbs in my mom’s ‘19 QX30 Luxe. I have no personal experience with LED headlight bulbs, so I have a few questions. I wanted to know the proper orientation for the LED chips. Should the chips face left and right, or up and down in the projector housings?
Also, from skimming through this thread, it looks like Hikari from Amazon seems to be the most popular. On other forums I follow, people really like Morimoto LEDs from Retrofit Source or VLed bulbs from a Vleds. Both run close to $200. Has anyone tried these bulbs?
My final question is will LED bulbs throw error codes, and if resistors would be necessary? I ask because I put LED bulbs in the brake/turn signal lights to my Grand Cherokee. It threw a code and would hyper-flash flash. The fix was to run a resistor.
Some LED bulbs allow you to adjust the beam by turning the back of the bulb assembly itself. The resistors are not like the ones you mentioned for taillights. They look like these for example (The rectangle that says Sealight). They are usually built into the bulb so all you have to do is plug it into your car and tuck the wires away.Thx for the response Alex! When you talk about adjusting the beam, I assume you are talking about doing it by adjusting the housing?
As for the built in resistors, do they get very hot? I know for my tail light LED resistors, I had to mount them on a metal surface to help dissipate the generated heat. I tested some cheap over the counter resistors and they hit almost 300F after 3 minutes of constant current. I ended up running VLed bulbs with their inline resistor. Their resistor hit about 180-200F running constantly for 3 minutes.
I honestly have no clue. I'm curious myself what that design is like.I posted this question to a reputable bulb vendor and I’ll post their reply as soon as I get it.
on a different topic, in the QX’s with factory LED headlights, are those LEDs replaceable or are they integrated up into the housings???
