This has been asked before... and i think we decided that they are all the same size.
You gonna get some dark lexus ones

- would look good on your colour
yeah - I've seen those, never been a fan of lexus style lights, but the dark smoked ones would indeed look hot on my car... might keep my eye out on ebay.
Something like this:
But with a bit of a tint on them perhaps...
I only asked, because just about 3 weeks ago I bought some afterburner style light masks, which don't fit - thought maybe there was a difference in size between the pre and post 2001 models... didn't think there was though.
In any case, I tryed to contact the ebayer that sold them to me, who didn't respond.
Tried contacting paypal and going through the dispute process, and they were less than helpful.
Dunno what else I can do, and thought that if they would fit a pre facelift Sei, then I might be able to flog em on - but if it's looking like they wont fit a 98-00 model, then there's no point.
They are a good fit to the shap of the light, and hug well, but they don't wrap all the way round - seem to have about an inch or so of material missing on the edge that wraps around to the side panels if you get me..
