Weak beam System seems to be chargering. Very weak beam, not sure if it is a faulty lamp or battery? Light is appox. 8 years old without a problem. help?

If the battery is old(2 to 2/12 years) the battery is sulfated and worn out inside. Going dead is just the nail in the coffin. Plus, a discharged battery will freeze in cold weather, allowing the ice inside to bend and break the lead plates inside, causing shorts to occur and will drain the battery after charging. If it were me, I would bring the battery somewhere warm for 8 hours, slow charge it, then have it tested. If it's more than 2 1/2 years old, I would just replace it.

what car, what year,? what model (wrangler?) im clueless
bulbs get weak with age
the glass in bulb (looks like silver paint)
this is normal for extreme usage.
replace the bulbs if dim. both.
if the car has covers in front of bulbs (not my 02 wrangler)
but newer cars have this crappy plastic in front,
it can be cloudy, there is a nice kit that fixes it (labor) at walfart. ask.

dim lites?
1 dim bulbs
2 cloudy lenses.
3: bad wire, bad grounds and bad connectors to lamps.
4: wiring hacked by kids wanting HID bs.
5: wrong bulbs, kids again.
6: corroded fuses, (12v at lamp do you have)?
7: bad combo switch or its ground is bad.

if you have 12volts across the dim lamp, you can skip 3 to 7 fails.

see your FSM for how they work. and wiring.
does your car have DRL? daylight running light option or in CANADA?
that be more heart ache.
and my jeep the highs and lows are never on at the same time.
the combo switch selects one or the other.
what it does in flash mode, not sure. need car year. and name.

all 3 power packs do that?
on 3 LT.?
what a load of bull 3 new LT, hope you didnt pay $1000 each.
2009 is not new. not by a mile.

running VISTA.
they are relics sure new to you and means XERO THAT!
id bet all 3 have bad batteries.
so now remove the batteries and see it now work ok.
on all 3.
see? what does that tell you.
yes, all batteries this old do not work, now.
none do.

out of warranty
hahjahahahahahahah now that made my day that joke
it can run widows 7, BTW

hp still support it. its out of warranty after year 2010 1 year old.

here is the fix.
buy one new battery
see it work on all 3 LT?
sure,
now you know that batteries 7 or 8 years old, really are a hopeless
place to be.
non one lasted that long.
or is totally weak
shorted
or is so bad it confuses the charger chip. as all do like that.

If the charge lite comes on when charging it means your transformer is still good. Replace the battery.

If you get no charge light transformer is bad, if this is the case (personally) i would replace the charger & battery for that peace of mind.
