Adding driving lights to E-450 (UPDATE)

Vehicles imported from USA to Canada must have driving lights. I learned on the Siennachat forum that all Toyota Sienna vans are manufactured with driving lights. For sale in US the driving lights fuse holder is left empty and the modification to allow them to be imported is simply to insert the fuse. Very sensible. Our 2004 E350 has no obvious post-manufacture modification so maybe the same thing applies to Fords.

I think you are mixing up things a bit.

I suspect the Canada requirement is for DAYTIME RUNNING LIGHTS or DRL.

Per Wiki (although not the greatest source of info it was handy to find) HERE

A daytime running lamp (DRL, also daytime running light) is an automotive lighting and bicycle lighting device on the front of a roadgoing motor vehicle or bicycle, automatically switched on when the vehicle is in drive, emitting white, yellow, or amber light to increase the conspicuity of the vehicle during daylight conditions.

DRL and "driving lights" are two entirely different functions.

DRLs typically used either the headlights (low beams) at a reduced voltage (does not burn at full brightness) or a separate low brightness powered, which MUST AUTOMATICALLY turn on anytime the vehicle is running.

"Driving lights" or "Auxiliary" lights are typically add on aftermarket lights which typically only supposed to be burning with main low beam only.. and are added on to aid the existing OEM low beam lights.

Some of these aftermarket lights are not allowed to be used for "on road" purposes since some exceed wattage/brightness limits for forward facing lights..

These are not required to turn on automatically but now days they are supposed to automatically turn off whenever the high beams are turned on.

Not to be confused with "Fog" lights which have a special purpose beam pattern which has a sharp top cutoff..

And yes, many vehicles may already have DLR harness in place, but may lack other needed parts like fuse, resistor (reduces the current through the low beams), relay(s) or in most new vehicles BCM (Body Control Module) programing enabled... So, your mileage may vary if trying to use the OEM wiring harness for DLRs..

Op did not really mention the reason for the driving lights so one can only guess that it is either for helping the OEM pathetic lights or possibly DRL.. My bet is fixing the OEM lights..
