Ever used H5024 headlights?

[luvbowties]

I don't wish to uncover a dead mule and kick her some more, but I just wondered if anybody has ever used GE 19428 - H5024 bulbs for a headlight upgrade? I found a comparison-chart for different, interchangeable bulbs on some internet site--sorry, forgot where--and the specs looked like they would make a simple-to-do, yet significant improvement in output. [If I can find the site, I will come back and post it.]

Thanks.
