If you want to save money, i suggest just cleaning the oem ones. I had experience with sanding the oem 95" teg lights, the finished product looked like glass.(really good) - sand paper 800-1000-2000, rubbing compound for less than $20 + hours of cleaning.
I was in a shop in LA and they had integra halo lights for sale for about $150 [in spring twothousandeight.]. I searched it up on ebay and it ranges from $80-$130. (oh btw it depends on your integra's year )
vs.
sooo you have to ask yourself, clean oem Vs. aftermarket halo.
