Procedure notes
This video shows you how to replace a burnt out rear turn signal on your 2007 GMC Sierra Denali. We recommend that you change both the driver and passenger side bulbs at the same time on your Sierra Denali as they get dimmer over time and if one is out, then the other one is likely to burn out soon. If the turn signal (also known as a blinker or flasher) blinks rapidly or doesn't blink at all or lights up without blinking when it is turned on, this is your Sierra Denali's way of telling you that the bulb is burnt out. Turn your hazard lights on and check the front of your Sierra Denali and then the back, whichever side is not lighting up is the side with the burnt out bulb.When changing the turn signal bulb in your Sierra Denali, be careful not to touch the glass portion of the bulb with your fingers as this will cause the bulb to burn out prematurely.

本视频演示如何更换您 2007 GMC Sierra Denali 车辆的烧坏的后转向灯。 我们建议您在维修您的 Sierra Denali 时，同时更换驾驶员侧和乘客侧的灯泡，因为灯泡随时间会变暗，如果其中一个损坏，另一个也可能会很快烧坏。 如果转向灯（也称为闪烁灯或闪光灯）快速闪烁、完全不闪烁，或者在打开时灯亮但不闪烁，这是Sierra Denali在告诉你灯泡已烧坏。 打开危险警示灯，先检查 Sierra Denali 的前部，再检查后部；没有亮起的一侧就是灯泡烧坏的一侧。更换 Sierra Denali 的转向灯灯泡时，注意不要用手指触碰灯泡的玻璃部分，否则会导致灯泡过早损坏。
