Do they fit right into the usdm 91 si's?
Like do the bulb's just pop right in no problem or are they different?

 

It's so funny, JDM corners....the crx "never" came with amber corners, clear only. Years ago, Vision (in Japan) made aftermarket models, then knock off companies made cheap no name copies that bolt into US cars. Try ebay, yes, they just pop in.

 

here is my install link/why not to buy cheap lights:
