I got a prelude without lights or bulbs. I bought lights and bulbs. Tried to plug them in and they didnt fit. The headlights require H1 (one prong) bulbs and the wiring for my headlights is for H4 bulbs (3 prong). My question is its a 2001 and why is my wiring H4? p.s. The lights work great with the H4 but I cant fit them in to the headlights. If you someone could answer this quick I would appreciate it. Thanks

 

And if anyone has an 97-01 prelude let me know if your bulbs are H1 or H4. Thanks

 

Because you need the white plug thing that th H1 bulbs connect to. If you need some, I have some extra's from Retrofits I've done. Just let me know. All 5th Gens. use H1 bulbs for High and Low beam lighting

 

Here's a pic for you. Just let me know how many you need, and I can ship them out to you
