If you don't own a test lamp, buy one . . . it will become your new best friend.
To ask a dumb question that may save some time, are they "plumbed" into the high beams (which they should be)? Were the high beams on when you tried flipping the switch on?
If you own or can get access to a test lamp, connect it to a good ground and check out the following:
* The input for the power on your relay should be labelled "30". Check with the light that you have power at this terminal all of the time. If it's not, check your power feed from the battery.
* The output blades on your relay will be labelled 87. There will be either 1 or 2 of them depending on the relay supplied. With the switch and the high beams on, check to see if there is power coming to these. Ideally check with a second person. The relay should make a clicking sound if it is working. If there is a click and no power coming through, you power feed from the first step was ok, then it could be a dud relay. If there is no click, then you need to check to make sure that everything on the line from the switch is ok.
* If there is power coming to the 87 posts but your lights won't go on, check to make sure that the lights have been grounded properly (you can check the power feed that you are connecting to the lights), that the bulb in the lights has been inserted correctly (or that they are in fact there).
* Assuming that there is no power getting to the relay from the switch to the post labelled 85, find somewhere inside your Jeep to ground your test lamp, turn your high beams on and make sure there is power getting to one side of the switch. Flip the switch and make sure it is getting to the other side.
I'm not familiar with the Lightforce wiring harness but if none of that works, sing out again with the symptoms and I'll have another go. Failing that, in the Feb edition of JAA, my article on installing a set of spotlights on your Jeep shouldn't be too far from the stands
