In case you didn't realize, you need EDM headlights to run H4 bulbs in a CRX. JDM SiR headlights use H4H bulbs, which aren't available in the US (ebay is your best option) but you can get the same bulbs I have in H4H, Darryl has a set that used to be mine. If you're staying with US headlights, buy four 9005 bulbs of similar quality and put them in, for the stock headlight super-bright win.
There are two types of EDM H4 headlights BTW, one fits the SiR front end (VT headlights) and the other fits the US front end (ZC headlights). They are all glass like the US headlights (JDM plastic FTL) and you can also get them with power adjustability.
