Cheapest and easiest is ebay. The "Silverstone" quartz halogens fit in the Miata and 96 dodge sockets, and are 30% brighter and more focused. HOWEVER, there may be some LED lights even better. Make sure there isn't an issue with our switches not handling the added amp draw (heat) if conventional bulbs are upgraded. LED's use less light, but I have not tried any yet...ANYONE?? The Silverstone's are still working great, and they didn't mess the Dodge switch up (unlike other upgrades forums say)...If ANyone on here knows about LED'S and has a site please SPEAK UP and send us a LINK! GL with it...Advanced (cheapest is Rock Auto) may have them on order...Post up new thread with your results and what you do please!
