Why are my headlights dimming for 5 to 10 seconds and then getting brighter

Dimming is not related to the RPM's and will do this in 1 to 2 minute intervals staying bright thankfully. It's also in the other electrical lights as well, but this does not affect the bikes running. Im thinking I need A new batterie.

SOURCE: Won't start without charger on battery.

when you charge the battery make sure that its cable is is loosen from the motor coz it can damage your charging system. on your case you have damage it already that's your light dims whenever you rev the rpm up. so change your voltage regulator of your charging system, charge the battery and it is done easy.

Sounds like you have water that is pooled in a connector or in the wiring harness water conducts electricity time to take covers of and expose areas and blow dry with air suspected area where water would settle relays multi plugs check each one for water.

SOURCE: i have a 95 fxstsb

well, its not the "circut breaker" aka the fusebox, so there has to be a problem with the regulator. when you say headlight "blows" do you mean the actual bulb burns out, the fuse burns out, or the light just turns off? it matters. on a side note, if your headlight stops working, its normal for all the other lights to get a little brighter due to the extra power for the headlight going to the others.

I agree.....The bad thing is you will have to replace both because the alternator will **** the battery
to 0 voltage..If it is bad...However..I would check all connections at battery and alternator.first...If it is just a bad connection
that you can repair... the battery will build itself back up again..If it hasnt been happening long...Although bikes are hard to work on......I have a 91- 883 sporster deluxe and even the negative cable is in a very tight area..
................Best of luck.......................hope this helps.......................metalpoet

Headlight are dim

check output of the alternator as there may not be enough current produced to keep the battery charged. Check drive belt tension and condition.

I just bought new headlight bulbs but one light is way brighter then the other, my left is brighter then the right and stays dim even when i turn on the night lights. whats the issue?

There is the issue with the wattage of bulb you have got for the vehcicle.

And also due to a new bulb it shines brighter then the old one.

get the old one also repaced to get the equal brightness

I have a CDA 7892 alpine works great but would like the display to be brighter seems a bit dim manual does not say this model can be adjusted or am i missing it any help thanks in advance

You didn't specify if you wanted the display brighter in the daytime while headlights are off or if it is too dim when the headlights are on, with respect to the rest of the instrument panel illumination. Too bright is easier to deal with but too dim is tough. If it is always too dim under but daytime and night time conditions the only way to improve brightness would be to very gently disassemble the front panel (easier if it is the removable type) and determine what provides the back lighting. If there are tiny LEDS you could painstakingly add more LEDS or swap them out for brighter LEDS. There could be a lot of guesswork determining if this or that LED was brighter than what is in the unit as built. It may just be easier to live with it as-is.

Headlight is dim in idle.

You need to see what voltage is at your battery at an idle, with a meter first.

This sounds like your alternator maybe going bad. When your alternator starts to go bad lights such as headlights, radio lights will go dim wipers will start to move slower but if you cut one of the things off such as the wipers the lights will get brighter for a few minutes then not long the car will shut completely down. Hope this helps.

06 honda civic are headlights always dim?

Well, if you truly believe they are dim, voltage drop test on the power side of the headlight circuit, and then on the ground side. Separately. If there is excessive voltage drop in the wiring, that would cause dim headlights.

If the headlights and dash are dim when u turn multiple electrical items on, then it is a bad Electrical Load Detector(ELD)

Good Luck

Right headlight is brighter than the left headlight

Probably a bad ground or bad connection on the headlight that's dim. Try wiggling the wires on the bulb connection if that's not the problem/ Try and find where that headlight gets it's ground.
