New bright housing (same as #5007 but for turn signal lights). Improves safety and appearance. A bright chrome surface stands out where it visibly separates the lens from your exterior paint. NOTE: Utilizes bulb holder removed from the old housing. Don't forget to order gaskets #5009/#5010 and a new #5257 bulb today. (Fits 1968-1973 GT's, up to chassis numbers ending in #3100995).
