So, you did the smart thing and purchased your new Volvo tail light bulbs from us and saved a bunch of money. Now you've got the trunk open on your S40 and you're looking down towards your Volvo tail light, and you have no idea what to do next. Usually your Volvo tail light will have some thumbscrews or a pair of rotary knobs on the housing. Reach down towards the Volvo tail light and turn those, and the back cover should come off. That'll expose the sockets for your Volvo tail light bulbs. The Volvo tail light bulb sockets usually take a quarter-turn to unlock, and the socket pulls right out. Volvo tail light parts tend to be fairly easy to remove and replace. That should tell you something about your Volvo tail lights: It's not uncommon to need replacement Volvo tail lamp parts. After all, with the exposure your Volvo tail light gets, along with the fact that your Volvo tail light operates on a bulb, which can burn out, it's no surprise that Volvo tail light components are some of our best sellers. But that works out well for you: When we sell a lot of Volvo tail light parts, we can keep the prices lower. If you have a more complex installation, like a Volvo tail light assembly, consult your owner's manual for more detail. Or better yet, pick up a Volvo repair manual. And when you need Volvo tail light parts, come here to get great Volvo tail light products, low prices, and fast shipping every time.
