During the first few days of operation, it is normal to see some moisture appear in your Acura TSX Headlights. This is due to the small amounts of moisture in the plastic and coating that are evaporated when the headlights are first warmed up during use. This sort of moisture is normal and should disappear within a few days.
To our knowledge, all of the Sonar (aka Spyder) and KS (aka Anzo) brand headlights we sell are street legal as mandated by federal law in the United States. That means basically that they are designed to the specifications set forth by the DOT (United States Department of Transportation). On occasion, DOT may test models to double check for compliance. In cases where these Acura TSX headlights fail (rare) DOT will have the companies issue a recall. For such headlights, we can take them back and refund you. For other brands, we can not guarantee DOT compliance. Also, please be advised that you may have local laws that may disallow these sorts of headlights to be used.
To be sure that no external moisture gets into the Acura TSX Head Light though, it is a prudent idea to silicone seal the edges. Clear silicone sealant can be found in any hardware store (and some auto part stores), and can be applied to the seam along the TSX headlights where the clear lens meets the rear housing. The $5-$10 is worth it in the long run to protect your investment.
These Acura TSX Projector Headlights, like all the other projector headlights, taillights and fog lights on our site, come complete with both sides, and should be street legal in most communities.
