Don't trust overpriced third parties for your genuine OEM parts. Not when you have INFINITI of Lynbrook in your corner. Side marker lights improve your vehicle's visibility to other drivers, especially during lane changes and in low-light conditions. These small but important lighting assemblies mount on the front and rear fenders to show your vehicle's length and position. The INFINITI QX55 and Q50 feature side marker lights that enhance safety during nighttime and inclement weather driving.

The Job of Side Marker Lights

Side marker lights emit amber light from the front fenders and red light from the rear quarters to make your vehicle visible from the side. These lights illuminate automatically when you turn on your headlights or parking lights. Federal motor vehicle safety standards require side marker lights on vehicles longer than 80 inches to prevent side-impact collisions. The reflective lens design also bounces light from other vehicles back to their drivers, providing passive visibility even when your lights aren't powered. Side markers work alongside brake lights and turn signals to create a complete perimeter lighting system.

What Causes Side Marker Light Damage

Side marker lights break when road debris strikes the exposed lens during driving. The plastic housing becomes brittle from years of UV exposure and temperature changes, leading to cracks and moisture intrusion. Bulb sockets corrode from water infiltration through damaged seals, preventing proper electrical connection. Vibration from rough roads loosens mounting clips and hardware, causing lights to rattle or fall out completely.

Recognizing When Replacement Is Necessary

Replace side marker lights when the lens shows cracks, cloudiness, or discoloration that reduces light output. Burned-out bulbs need immediate replacement to maintain legal compliance and safety. Water or condensation inside the housing indicates seal failure and requires a new assembly. Aftermarket side marker lights often use inferior plastics that yellow quickly and bulbs that don't match OEM brightness standards. Genuine INFINITI side marker lights maintain proper color temperature and meet all federal visibility requirements. Keep your vehicle running like new with INFINITI of Lynbrook's top-notch components.
