so age has nothing to do with it then. it's a us problem
The harnesses starting having DRL in '94 or 95 in the US since all YJ's were built in Canada but they lacked the DRL module. I don't think Jeep ever adopted DRL in the US as it is not a requirement.
Honestly though, I think DRL is a bad idea. When it first showed up people noticed it. Now, it's blended into the scenery and is no different then when it wasn't required. The bad part is, motorcycles aren't noticed as much as well since they are required to have their headlight on. Now they just blend in like the cars.
In any case, I order the Hella E-Code housings and the 60w/55w H2 HB2 bulbs. Hopefully they will be here before Thanksgiving.
