" dim headlights "? None of your lights should be 'dim'. You have 4 lights.

Side Lights.
Daytime Running Lights (DRL)
Low Beam Headlights.
High Beam Headlights.

Here are the fuses, check fuse 5 and D although they covers more items than lights. Your best bet is to find a good local auto-electrician.

bad connection or bad earth check all connection or bulb

Check your head light bulbs, your truck has the dual filiment headlight bulbs one per side which does both high beam and low beam, 9007 bulbs.
If the low beam filiments are burned out only the high beam will work.
Also look into finding out if the headlight switch is gone bad.
The headlight module and or drl module maybe defective.

sounds like your dim to bright switch went bad

Test the leads to the bulbs while the low beams are on and then when the brights are on. If you have good bulbs & fuses with no power on low, the problem is most likely the bright/dim switch.
Not exactly sure of the Acura layout, but the covers over the steering shaft should remove with several screws to allow access to the switch (usually the turn signals are also the bright/dim switch) Test the leads out to the headlights from the bright/dim switch, that will tell you if the switch is bad.
Airbags are closely involved with this removal/replacement, it is NOT recommended for a amatuer to undertake.

Look under the hood.
There is a large relay which should have some info about lights on it.
I had this exact problem with my dodge ram

It's the dimmer switch in the column.

check your head light switch
