So basically I got new led lights and I find that even if I rotate the bulbs or try other ways of installing them they won’t light up the middle of the road on lows and on brights its almost like one beam into the left lane like I am trying to blind them. If you happen to know a solution or think you might please tell me. (The lights I got were Raxiom Axial Series 6000K LED Headlight Bulbs; 9007 on American Muscle)

Sorry to say, this is a known and common problem.
Your existing lead lamp reflectors were designed for a specific type bulb, mounted and an exact location (distance from its base) withing the housing. Researching bulb vs beam patterns would have saved you the problem you see here.
The fix? Put the old bulbs back in and return the LEDs...

Exact what Clever said. This has to do with parabolic shapes and where the source of light is coming from. Cheap LEDs will show how right away that they will not work in a reflective housing head lamp. You won’t see well and you will just blind everyone else.

#

Return them and get high quality halogens or invest in some projector head lamps.

Cant put LEDs in a halogen housing. Good that you have the decency to check the pattern instead of going around dazzling other drivers.
I recomend putting low beam back to halogen and keep LEDs in the high beams.

In theory, LEDs with a matching focal point of the halogen bulb they’re replacing could work. In practice, I’ve never seen a set of LEDs which worked like that. I have seen one set of LED bulbs that advertised the focal point was a match, but they were $200/pair, no idea if that claim was accurate

This is it. If you order LEDs from Diode Dynamics for example they should work

But like you said, they are gonna cost ya!
