Depos are glass.It's hard to beat the longevity and clarity of the glass vs. plastic aftermarket.
I took a rock to one of my glass original headlights. still works, but looking for a replacement.
for a stock headlight, especially a 20 year old one, the performance is really good.
I would do a bulb upgrade over a complete replacement unit.
You can use the 9011 in the low beams too for more light. I've never been flashed by others.Great high beams, lows weren't all that.
