For those of you looking for higher quality H4 conversion housings...

[Big Body LX]

They're made for a Nissan 240sx but the 240sx and 3rd generation Accord use the same housing!

These are GLASS not the PLASTIC that other companies use!

They're the second item if I remember correctly

Mine is glass... but the reflectors on the inside of the housing doesn't have as many angles as the plastic ones do.

The ones with the faceted reflectors are called "Diamond Backs" for that reason. It gives a neat effect, but what it does for the light ouput patter I don't know.

The ones I bought from Midnight Moose had glass lenses and are very similar to the Bosch ones shown. They were half the price, though, and have a good output pattern.
