98 Mustang Headlights install issues

[lvi56]

I've been trying to install some angel eye halo LED headlights on my mustang. First of all...how they heck are the headlights held in? is there an easier way to get them on or off without snapping plastic pieces?

I attempted to wire the LED's by myself following the how to video on autohow.tv. Did it exactly as he did it in the video but they never came on. This is no big deal as they are a luxury, but it's frustrating.

The main issue is the main lights themselves. Parking lights/turn signals work perfectly. However, only the right side headlight works perfectly, the left side light only lights up very dim. I've included some photos of this issue.

The left side is the top link, the one which is dim when either the dim or brights are on.
2nd is both with regualr dim headlights
3rd is when brights are on.
bottom is the right side, appears to be working just fine with regular and brights.

Any idea on this? wiring looks the same for both of them. Maybe a bulb issue? bulbs came with the headlights, bought new off ebay.
thanks!

So I took the old bulb and put it on the left side harness...works perfectly. Then I took the left headlight unit (dim one) and connected it to the right side harness, works perfectly. wth...?
