252H 6 #1 Posted October 12, 2014 My 520-H 1991 has a blinking left front head lamp. The other side is fine. Is the bulb going out? Share this post Link to post Share on other sites
GM_Man 47 #2 Posted October 12, 2014 Check the wires that are attached to the bulb. Sounds like one of them may be loose. 1 Share this post Link to post Share on other sites

Racinbob 10,277 #4 Posted October 12, 2014 (edited) Maybe your 520 is flirting with you? Seriously, GM Man is probably right. I've seen defective bulbs do that but not for long. Make sure the conductor connection to the connector is good as well. Edited October 12, 2014 by Racinbob 1 Share this post Link to post Share on other sites
