I have a 2007 sportster that seems to skip neutral goin from first to second gear and from second to first both with the engine on and off. The gage N light doesnt even flash when passing through those...

Hey chris , i wouldnt worry about the neutral light coming on when your shifting thru the gears on acceleration. If your light isnt working or you missing neutral , try adjusting your clutch. Then if that isnt the probably find your neutral switch connector and ground the terminals together and your light should pop on . If not replace the switch. Im not sure what gauge you have there might be bulb for the neutral light also .

Samsung dlp tv will power on then shortly after I have three lights flashing and it shuts off with lights still flashing, this happened back in april, I replaced the bulb and now its doing it again....

This is a suggestion and not a solution to your problem.

I would watch from the side or rear while someone tries to turn the set on: Does the lamp light even for a few seconds?

Second: I would also with set unplugged remove lamp cartridge and look at the color wheel: is it intact and not shattered?

The color wheel can make a high pitched or fan like sounds before it fails.

If after you examine the color wheel you find pieces are gone etc it is your problem and not the lamp; it faces the lamp and if you look carefully you should be able to see if it is intact; I attach a photo of it for you.

Before you rate this information let me know what you find or if you have questions.

Front passenger head lights keep flashing in and out

If you haven't already done so change the bulb and see if this corrects it. I broken element in the bulb will do this when the element bounces up and down and makes brief contact. If you have tried this then it could be caused from a broken wire on the headlamp harness or a bad headlamp socket. I would first remove the headlamp leaving it attached in the socket, with the lights on shake the harness and see if you can get the bulb to flash. If it does flash inspect the wires going to the headlamp socket for and damage or breaks and inspect the socket itself for a loose fitting bulb. If you find bad wiring repair it using water tight **** connectors that will need to be heated to seal the wires. If you find a bad or worn socket from excessive heat then contact you dealer or local junk yard for a replacement and again use water tight **** connectors or shrink tube.

Left low beam is out on my 2006 dodge ram 1500 4.7 v8 the bulb isnt blown and the high beam works low beam does not

I'd still vote for the bulb being bad. The high and low beams use two different filaments, so unless the bulb is physically broken, it is common for the low beam to be bad whilst the high beam is good.

That's why you see some people driving around with their high beams on -- they don't want to get stopped for a 'light out' citation..

When you take the bulb out to replace it, be sure to look at how it is mounted before removing. You don't want to accidently adjust your headling out of kilter.

good luck
