In the second image, I've made some notes, let's talk about them. Notice the halogen bulb on the right has two sets of filaments. One operates during normal light, the other operates the high beams. The LED bulb is exactly the same, meaning it is CRITICAL that you mount the removable ring (part with the O-Ring on it) so that the flange marked "A" points up, in relation to your vehicle. If you fail to do this, your beam pattern will be incorrect, and your high beam setting will not work properly. If you're not sure which way is up on your new bulb, please look at the part of the bulb marked "B." Note the "fat end" versus the "slim end." This is the easiest way to tell where the "A" notch should be facing or aligned. "Fat end" is the bottom of the bulb, and the "slim end" is the top. I suppose you could adjust the bulb, but adjustment is limited to 90 degree increments, so I don't suggest it. If you install the bulb upside down, you will have a permanent "high beam" effect in normal headlight functioning, and a beam spread of about 2-6' in front of the vehicle (fairly useless) with high-beams activated. Remember when installing that the silver hex screw's drive can EASILY strip, so push down hard with your wrench while you twist, and don't over-tighten. In almost all cases you want the LED's cable running down, or in the direction of the street underneath. The lighting is very bright, and signs, even far down the street glow. High beams go even further. I bought a different brand for my fog lamps with the same 6500K color and they match perfectly. Good Luck.
