I recently installed some good looking brand off Amazon in my 01 base. The other commenter was spot on about the retaining bracket.
The lights were fine, but immediately after I started getting this issue.

Now the weird thing is, I swapped back to only halogen bulbs and the issue persists. I spoke with my indy and he thinks its the turn signal stalk and assembly, and that it just happened to die when the LED's were installed.
I haven't fixed it yet, and I'm planning to make a separate post to investigate further.
So in summary, light projection was decent with LED's, but I had an unexpected issue pop up that may or may not be related.
