nightmare7306 11 Report post Posted October 22, 2014 I have recently bought a '70 Mach 1 and the front marker lights only work as signals. I have seen other '70s where these lights came on with the park lights. Should these light up as park lights or have the others I have seen been modified? The rear markers work as parks and signals. Thanks for any info you can share! Quote Share this post Link to post Share on other sites
