Is it the 168 bulb in the main headlight housing. I have replaced the hi/los with Sylvania Silverstar Ultras and Fogs and want to get rid of the yellow DRLs/Parking light. Just wanna check if they are the same thing.
You must have a 05' or newer truck I'm guessing. That's when they put the daytime running light in the inner corner of the headlamp housing. On my 05' I took out the halogen bulb, and replaced it with an LED bulb which gave a more pure white that matches the Silverstar color much better.
