Keep blowing headlight and spot bulbs on 2003 Heritage Softail

Started last year when bike got soaked at bike fest. Low beam and spots went out. Replaced head light, worked for a while on low & high beam then low beam went out again. Now high beam has gone out. Just hooked up new bulbs on both and they all work. Afraid its just gonna eat up these too and don't want to keep buying replacement bulbs. Could there by a short or something causing the bulbs to burn out so quickly?

Dale is right on it but a good idea would be to separate all your harness plugs and check for corrosion etc. There's a product called ACF-50 which comes in aerosol or grease that prevents corrosion in electrical plugs. Check it out online?

A good start would be to check the VOLTAGE at the headlight. If at any time the voltage exceeds 14V (at all engine RPMs), replace the voltage regulator.

SOURCE: How to wire a tach on 05 heritage softail

Locate & route Black lead to ground / 2004-later softail: On the frame strap under the seat directly in front of the battery.

Locate & route the pink lead to Signal / For 2004 & later FXST/C/I The #3 cavity in the connector {39b} on the back of the speedometer. The socket terminal on the signal (pk) lead fits the #3 cavity.

Locate & route the Orange and white lead to power / Ummm.. it's saying for 2004 and later to adapt to the fuse block For earlier [ For 1996 to 2003 softail: locate the power lead (o/w) in the tail lamp pin connector {7a} under the seat behind the right rear corner of he battery.] "here you are looking to run it to a fused line, not directly to power/battery" I hope this helped.

2003 altima headlight fuse keeps blowing on passenger side

The most likely cause would be a wire chaffed through and shorting out on the body. Pull the plug in off the light and start tracing it back looking for a bare spot. Tape it up with electrical tape and try to re-route it so this doesn't occur again. Hope this helps.

2006 Trailblazer low beam headlights out high beams work.

Bulbs are like people - some last a long time, some croak early.

Meanwhile the part they plug into can be cleaned out and restored if metal is still there.

Replace right low beam headlight bulb on 2003 Golf

The back of the headlight case has a slip-clamp, then you can remove the back of the case. Twist the socket the wire is attached to until it releases. When putting in the new bulb, be sure to wear gloves. The bulb will develop a hot-spot if it gets any oil from your skin on it. Both of my low beam lights went out at once, which I am told is very unusual. It cost me $30 to replace them myself!

2006 colbalt keeps blowing low-beam headlight fuses

The power wire for the low beams is shorting out somewhere. You will have to trace it back from the headlight. Pay close attention to any place it pass through or rubs on metal. Tape the spot up when you find it and move the wire to a better location so it doesn't rub anymore. Hope this helps.

2003 FLSTCI high beam works, low beam and spots do not work. Do I have a plug problem under the gas tank or a problem in the H/L handlebar switch?

sounds to me like the low beam filament in the headlight bulb is blown test for voltage on the yellow wire at the headlight with it set to low beam if you have voltage here you more then likely have a blown low beam filament
