It's that season again, so if you want to get on your teenager's good side, then brush up on your car accessory knowledge with this tutorial. With a little jargon in your pocket and a good set of ears, you'll be able to decrypt what they want under the tree for Christmas.

Lately, it's all about the wheels - what showcases the tyres and car the best. Some rock big honkin' shiney chrome lug nuts while others go for aftermarket center caps. Others slap on a set of stylish spinners, adopting the fashion of hip-hoppers like 50 Cent, Nelly and Redman. LED lights are being seen more and more on the streets at night. It will certainly get you noticed.

Some Terms You Should Know:

• Spinners are wheel accoutrements that move on roller bearings, giving the wheels the visual impact of unexpected movement. Because rim spinners work independent of the outside rim they rotate even when the car stops at a red light, energized by the law of momentum, sliding along on their bearings with little opposition from the wheel itself.
• A factory center cap is what is in place in the center of the wheel when you buy the car from a dealer. To make your rims more appealing, you can purchase high-style aftermarket center caps that will set your car apart.
• Center caps can be snapped into place when upgrading your tires with aftermarket rims. The caps cover the center of the rim and can have all manner of patterns - domestic or foreign logos, even a concept design. If you want to save some cash on a set of aftermarket center caps then swing by a salvage yard and take a look around. Don't forget the web; there are plenty of suppliers who would be happy to help you find the perfect set of caps.
• Aftermarket rims are cosmetic wheel accessories to add style and individuality to your vehicle .  Aftermarket rims come with center caps but you can obtain a set of unique center caps to really make them stand out.
• Hub caps are wheel covers that protect the lug nuts and rim by mounting to and covering the whole rim.
  
• Small LEDs can also be added to your rims. The LEDs emit a glowing light and are powered by small long-life batteries.
  
• With wheel spacers you can add additional width to the wheels, moving them a little closer to the fenders. This improves handling and visually adds a more aggressive presence.
