Check fuses and bulps.
low beam
High beam headlights reveal objects at a distance of at least 450 feet away. High beam headlights allow the driver to view obstacles in the road much sooner than low beam headlights.
I was looking at the 1996 Mercury Grand Marquis Owner Guide and it shows that you can change each of the ( 4 light bulbs for the 2 low beam and the 2 high beam headlights ) ( the low beam headlights take bulb # 9006 ) ( the high beam headlights take bulb # 9005 )
The switch is broken. You need to replace it.
I know that if you move the turn signal lever ( which is part of the multi function switch ) away from you it turns on the high beam headlights and if you move it towards you , you only have low beam headlights ( and if you pull the turn signal lever all the way towards you and then release it the high beam headlights will flash each time you do that )
9006 for the low beam, 9005 for the high beam
Dim headlights form high beam to low beam
I just fixed this problem , it was my daytime running light module
It sounds like the low beam/high beam switch is bad. Fuses are not the problem since they are built into the headlight switch and would cause headlights to blink or not come on for both high and low beam headlights.
i have a 96 olds achieva and my high beam light was flashing, i checked the headlights and one of my low beam headlights was out. once replaced the flashing stopped.
Perhaps he is in a large vehicle and his lights are already on low. All you can do is decrease speed and try to stay on the road. More flashing and he may show you his high beams!
