1986 Subaru XT - running light issue

I have a 1986 Subaru XT GL-10 Turbo and my running lights are acting up. Heres the issue.

When I press the running light button the running lights work just fine. When I press my headlight button the running light button on the dash clicks off (basically the two switches cant be pressed at the same time). Brake lights and everything works fine. So when the headlight button is on the running lights are off. I was pulled over for not having them on so any help would be appricated.

I do not have this switch on my 92 Loyale.

I recomend you visit www.ultimatesubaru.org. This site is great! Go to the "Older genertation". I am pretty sure you will find everything necessary there.

Good luck,
