D3S Traverse Headlight bulb Replacement

Hello , I am offering the service of changing out your 2021 Chevrolet Traverse headlight bulbs. I could do a single bulb or both light bulbs . I offer this service because the headlight on my traverse recently went out , and i called the dealership on cost to replace it. They quoted me at 950$ for 1 single light. A 3rd party shop quoted me at 400$-450$ also for one light . I’m not too sure why they are expensive to replace . But I can do a single light for 200$ or both for 300$ I can possibly drive to you depending on location. I do not order or have lightbulbs . The website I got mines from are posted in picture . New bulbs are not like your classic style they are D3S depending on vehicle . They worked good and I thought were very fair priced for a set. Reach out if you have any questions! Feel free to call dealerships and 3rd party shops . I’ll wait for your message ! Thank you !
