Question Available Fog Lights

Hey all,

I purchased a '17 Terrain w/o fog lights.

I'm wondering if there are fog lights which are affordable and available (preferably very bright 6000k temp).

Any help/suggestions would be appreciated.

Also, how difficult would it be to install myself?

Thank you!!

FYI, degrees Kelvin does not equate to brightness, but color. The brightest and whitest will be in the 4300 degree range.

 1. Disconnect the harness (1) from both lower lamp assemblies (2).
Object ID: 4446484Click here for detailed picture of the image.

 2. Remove and retain the bolts (2) securing the left and right front lamp assemblies (1) and remove both assemblies from the front fascia.
Caution: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

 3. Using the previously retained bolts (2), install the new fog lamp assemblies (1) to the front fascia.
Note: Left and right fog lamp assemblies are not interchangeable.

Tighten
Tighten the bolts to 2.5 N.m (22 lb in).
Harness Install
 1. Disconnect negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
 2. Remove the underhood electrical center (UEC), to access the designated connector below it. Refer to Accessory Wiring Junction Block Replacement.

11. Remove the ground nut (4) from the inboard side of the right shock tower.
12. Attach the fog lamp ground eyelet, on top of the existing ground circuit (3), align crimp tangs to minimize overlap, install the fastener and torque to 10 N.m.
13. Reinstall the air cleaner assembly. Refer to Air Cleaner Assembly Replacement or Air Cleaner Assembly Replacement.
14. Use the included tie straps every 150 mm to 200 mm starting from rear of connector, secure the wiring near each fog lamp and across the base of the radiator. Secure the wiring so that snow and ice accumulation will not pull the wires down. Cut off excess tie strap tails.
15. Connect the left fog lamp.
16. Connect the right fog lamp.
17. Reinstall front fascia to vehicle and connect electrical connections. Refer to Front Bumper Fascia Replacement.
Inspect to see if Circuit 1317 is present at BCM

Note: The installation of this accessory fog lamp kit requires programming and configuring of the vehicle. This is done with a Service Programming System (SPS-TIS2Web). The installer needs to call TCSC to obtain a VCI number. United States 1-888-337-1010 Canada (English) 1-800-828-6860 Canada (French) 1-800-503-3222. The Techline Customer Support Center will provide programming instructions and changes to the vehicles calibration settings. You must provide the vehicle identification number (VIN) of the vehicle to be programmed and the authorization code when calling TCSC.

 6. Using the Scan Tool with a MDI, and (SPS-TIS2Web), update the body control module (BCM) calibration file and the instrument panel cluster (IPC) to activate the front fog lamps and the front fog lamp telltales
 7. Test the function of the front fog lamps and the front fog lamp telltale. Fog lamps work with park lamps and low beams and not with high beams. (See checklist below).
 8. Reinstall any previously removed components.
 9. Aim the fog lamps. Refer to Fog Lamp Aiming.
