Hello. I've decided that I'd rather not be driving around pretty much blind at night and started researching on upgrading these lights. However, I'm a little confused as there seems to be a blinding array of lights available.

Is there a difference between the 1987 headlights as opposed to, say, the 1994? Didn't they all share the same body type? I've seen the Depo ones go from $139 to $170 a pair. What would the difference be? Some say that it won't fit my 1987 body.

I get that there're differences between the ones with wipers and the ones without wipers, and my understanding is that all I'd need is another body panel without the hole, or I could just fill up the hole on my existing one.

But what about the vacuum control? Can I just install the light without it? And finally, the oft-cited "citylight". How is that activated? Does it come on with the lifting of the ebrake like other cars?

Thanks!
