Aftermarket LED taillights off my 2003 Silverado. Got them off Amazon 3 years ago. Have worked great and had no issues out of them. Just not in love with the look like I used to be. The taillights, brake lights, and turn signals are built into the light housing and have stock pigtails on them. Only bulbs needed are reverse lights. Should fit 03-07 classic Silverado. Below is a link to Amazon with more pictures and descriptions. Feel free to call, text or email with any questions.
$75 Without the LED reverse bulbs
$95 With the LED reverse bulbs
