I had a set of 6000k in my 03 dodge ram. The rams are known for their crappy headlight spread patterns to begin with.
I just bought some cheap sets off flee bay for my headlights and fogs. I absolutely loved them!
I starting having ignition problems with them. So,e times they would fire, other times they wouldn't.
These were simple swap out bulbs with ballasts so the spread of light on them was extream! I'm surprised I didn't ever get flashed honestly.
Well since I started having ignition problems, I decided to spend the money and get projectors to replace them along with new high quality digital ballasts. I gotta tell you, the projectors are worth their weight in gold!
The spread pattern is MUCH better and doesn't blind everyone I pass. It took some time to get them right but worth it.
The kit I got required me to split my headlight assemblies and bolt in the entire projector housing. I opted for projectors without halo's. halos look good on cars that come with them, but I fel they look goofy aftermarket.
These projectors also have a solenoid in them for high beam function. When the high beams are on, it flips down a little shield and let's all the light out..absolutely insane! These things light up signs over 1 mile away!
I say if your gonna do HId's, do them right. You'll be amazed with the differences.
