Flyin Miata is running a group buy on Bosch 7" round E-code reflectors. My set of Hellas was $90 a couple years ago, so a pair of reflectors with bulbs for $50 is a pretty good price.

Thought I'd give a heads-up because I know I'm not the only one here with a Miata. A whole bunch of other vehicles run 7" round lights including some Jeeps I believe.
