    I just checked all of my fuses on the fuse panel by the drivers door kick plate and all are good. Looking for a relay or switchor hidden fuse as suspect. Just started surfing the web to look for ideas to test. My high beam indicator dosn't come on. Does yours? Just happened last night.

    I have the exact same problem. I have checked all my fuses and they seem good. This happened on a 1990 Toyota truck I owned and the solution seemed to jump some switch that was located under the steering column. My brother is an electrician and did some tests then added another wire. Presto, the lights worked. Don't know what he did. Any thoughts?

Thanks cyblet!
I didn't think it was such a simple problem, but i usually drive with the low beams on all the time....turns out they were both blown out, and the high beams left in tact....solved the problem for about $22 in new bulbs.

Your headlights have two bulbs in them one for low beam and one for high beam. I bet the low beam bulb is burnt out on both headlights. It's not uncommon to have a bulb go out at 50000 miles. I would change 1 light and see if it now works or take it to a local mechanic and have them check it.

It is entirely possible for both low beams to be out have you verified that there is No voltage on the low beam electrical circuit of the headlights?

Well the high and low beam lamps use the same fuses, and the dimmer switch handles the ground circuit. So I would check the dimmer switch if both high beam bulbs are ok.

Dash goes out when i turn head lights on


This sounds to me like you may have a faulty headlight switch. If the switch is on the steering column, you will need to replace the whole multi-function switch assembly, if it is on your dash panel, you should be able to just replace the actual headlight switch. Hope this helps.
