I have a blown bulb and since I have to replace I was just wondering if there were any factory spec looking halogen bulbs out there anyone is using that they would recommend? Thanks.

 

You can get cheap halogen sealed beams almost anywhere. Check your local parts store.
Or, you can get Hella E-code housings that have the factory style, fluted glass with H4 bulbs. I have had 2 sets and love them.
