I live out in the country where it gets real dark. The stock 55W high beams aren't cutting it. Will there be any harm in installing 100W or 130W high beam bulbs instead of the 55W?

 

just going off quick research via google, the first gen TSX uses an H1 bulb for the high beams. this is a Halogen bulb, that can generate heat as well as lumens with increased wattage.

I would look out for signs of plastic melting, if you do decide to purchase a higher wattage bulb

 

I agree, meltage is by far the biggest concern.

@ifixjetz1, I also live in a very rural and dark area, and am surprised the TSX high beams are insufficient. Do you have night vision issues?

 

Option 1:
I installed Sylvania Ultra low beam bulbs in my son's Accord an his mother's (ex-wife's) Odyssey.
The bulbs produce MUCH more light and it's whiter. They both noticed the increased visibility distance.
The only negative aspects are cost (~$55) and longevity (~1.5 years).

Option 2:
I suggest using 55 watts as you limit but search for a H1 bulb that produces more light at that power limit.
Amperage limit is approximately 55W/~13.5volts = ~4amps.
Perhaps a LED bulb.

 

No, I don't have night vision issues, I think it is since the low beams are HID, and the highs are halogen that the HID brightness cancels out the halogens. I may look into the brighter bulbs like the silver stars, or ultras.

 

It doesn't work that way, extra light is still extra light. I've had four different cars with HID low beams and halogen high beams.
