Sunpie LED headlights upside down

Question I just bought my daughter a 2024 wrangler and she has these Sunpie LED headlights , on hers the low beams are on the top and bright on the bottom are they in upside down ? Or is the wiring wrong ?

Traditionally the low beams are on top so they can shine down and high beams are on the bottom to shine out. In side-by-side configurations the outside light is low and the inside is high.

Some of us old farts remember the days of DOT standardized sealed beam lights.

Even on later lights with combination hallogen bulbs, the upper part of the light would illuminate for low beams and the whole light would illuminate for high.

Our first ride at night was tonight , and everyone was flashing us , there’s no lift on the jeep.

Aftermarket light are anyone's guess. Assuming they are genuine and not eBay knock-off someone may have jacked up the installation or they might not meet DOT standards. I don't see anything on the website about being DOT-compliant, but it looks like there's a beam height adjustment on the back of the housing.

Our LJ came with some crappy LED headlights and everyone was flashing us until we replaced them with KCs that met DOT standards.

Ok the way the headlights are designed to install is one way only, plus the plug for wiring is only one way, it’s impossible unless the unit is defective. But I suspect that the headlights are aimed incorrectly. Go on YouTube and look for your model Jeep headlight adjustment and follow the instructions, then lower each side when lined up 25’ from a wall. The low been cutoff should not be any higher than the center of the headlights minus an inch or two. Then see if your flashed.

Locate headlight among instructions on the Internet and check these themselves. Assuming normal hardware, have a Torx driver ready to make adjustments.. You need a truly flat and level surface to park the vehicle on, with the distance from the headlights, to a flat & vertical wall that is white or at least a light tan color. If this is outdoors, then your adjustment work will have to be done when it is reasonably dark outside. You won't see enough if any. of the fairly sharp low-beam pattern on the wall in daylight or even around sunset to precisely do the adjustments. I would get the vehicle in position during daylight and leave it there until suffiiciently dark to check the adjustment, and alter if necessary. Most of us do not have the required space inside a building to do this work.

The only trick here is getting your vehicle driven to the required distance from the wall, SQUARELY. This may take a few tries to get the front of the vehicle (headlights) within 1 or 2 inches of being parallel to the wall. Just repeat as needed until you get it as square as you can to the wall or surface that you're going to use for this work. Once you start checking and adjusting, it goes really quick.

With instructions available on the Internet, you will find all of the steps to be quite simple. You need a tape measure. I use blue masking tape on walls to mark where the aiming must be.

If you later change the height of the vehicle, the headlights obviously need to be re-adjusted.

The critical factor is the downward angle of the low beams pattern. That, is what will eliminate other vehicles coming toward you, from flashing their lights. If Officer Friendly is squaring off with you for blinding him or her, they may turn around and pull you over. And maybe look for other infractions. Not likely really; they have bigger fish to fry but if they have a moment, might tackle your issue. I might imaging a state trooper could really get fussy if they don'e see the surface of the headlamps indicating DOT and SAE approval. Now any manufacturer can mold that into the surface and these days, likely get away with it. The honest manufacturer will have met the specifications guidelines to insure their lamp, and lamp housing are correct. But still require reasonably precise aiming when installed. High beams - these are sort of like flamethrowers that only have some amount of containment of their beam. Used only when no oncoming vehicles are in some local range that we all know will blind them. At least if the headlight is aimed for low beam spec, the high beams won't be pointing to the sky too.

Don't want to do this work? Take it to a professional shop that has really good aiming equipment for headlamps. And other. If you replaced a windshield and have any of the electronics that decide how to make crash imminent decision for you (WHY), well they can adjust those devices to work properly again too. Change of winshield glass can require this. sort of of work. And ithat equipment work will be expensive because of labor time and the equipment cost to do this adjustments. But headlight aiming is a simpler and faster task. A shops time advantage is that they can setup the distance and parallelism a lot quicker. Hopefully the quality of reflector, or in your case I thin, projector optics of your headlamps can have the low beams adjusted well.
