DAYTIME RUNNING LIGHTS
®
Cole Hersee Co.
Daytime Running Light Module (DRL) No. 48600
For 12 VDC electrical systems only.
Important: Read instructions entirely before installing.
The Cole Hersee DRL module is a fully automatic control that
activates two LOW beam headlights in a reduced intensity mode
for daytime operation. It is automatically activated, with a ten
second delay, by turning the ignition switch to the ON position.
The DRL remains active until one or more of the following
conditions occur:
1. Headlights are turned on manually.
2. Parking brake is activated.
3. Ignition switch turned to off.
The DRL function returns when conditions 1, 2 and 3 are removed.
Vehicle Requirements: The DRL module can only be used in
vehicles having a 12 volt system. Vehicles not suited for DRL
operation include those with concealed headlights or headlights
that are activated by grounding the low side of the lamp (low side
switching). These vehicles include, but are not limited to, the
following: Mitsubishi, Hyundai, Toyota, Suzuki, Subaru, Colt,
Vista, Challenger and Sapporo. Consult your vehicle dealer or
service technician if you have questions.
Installation: Prior to installing, check headlamps for normal
operation and repair if necessary.
Mounting: The DRL module should be mounted in the engine
compartment near the battery and one of the headlights. Drill two
1/8 inch holes using the module as a guide. Attach the module with
the two #10 screws provided.
Wiring: Use the plastic connectors provided or other suitable splices.
Connecting the wires (see diagram of typical wiring, page 4).
The black wire of the DRL module must be connected to vehicle
ground. An easy way is to attach the black wire to the headlight
ground wire. Any other vehicle ground may also be used, such
as a metal bolt which firmly connects to a metal part of the vehicle
chassis. Clean off any rust or paint from the point of contact.
The white wire must be connected to the LOW beam feed wire going
to the headlight (see diagram, page 4).
The green wire must be connected to the HIGH beam feed wire going
to the headlight (see diagram, page 4).
The blue wire must be connected to the vehicles positive 12 volt side
of the ignition coil or a 12 volt wire which is switched on by the ignition.
A typical location for the connection is the positive 12 volt side of the
ignition coil.

The yellow wire is an optional disable for the DRL module. It
provides a means for turning off the DRL while the engine is
operating and the vehicle is parked and the parking brake is
engaged. This wire should connect to the low side (switched side)
of the dash mounted brake indicator lamp. Access to this wire is
usually available at the low brake fluid pressure switch located
near the master brake cylinder or at the parking brake itself. If this
function is not wanted, cut off the yellow wire and cover the end
with electrical tape.
The red wire provides the power for the LOW beam headlights in
the dimmed mode. Connect the red wire directly to the battery
(positive 12V terminal) or a battery distribution block.
Final Installation Tests
1. Start the engine. Approximately 10 seconds later the LOW
beam headlights should illuminate at reduced brightness.
2. If the optional parking brake inhibit feature was installed, test by
engaging the parking brake. The LOW beam headlight should go
out and immediately relight upon releasing the brake.
3. Test headlights for normal operation by manually turning on the
headlights. Exercise the high/low beam switch. Both HIGH and
LOW beam lights should operate at normal intensity.
In the highly unlikely event that the electronic power switch in the
DRL module should fail, the headlights could remain ON with no
way to turn them off except to remove the fuse from the DRL
module. If this type of failure occurs, the DRL unit needs to be
replaced.
