Turn Signals
« on: August 11, 2005, 08:49:32 AM »

I noticed last night that when I turned on my right signal that the fairing indicator was flashing rapidly. Looked at the signal this morning and to begin with one of the tabs on the smoke lense was broken. The bulb was black with the amber tinting basically melted off. Obviously water was getting in due to the tab being broken and it shorted the light. Now I need a new chrome housing as well because the chrome came off of the inside of the housing? Weird!

When H-D went to the small "bullet" turn signals, they changed the design to what we call in the auto business a "wet" design.  The old signals had a gasket between the lens and the housing; the new ones have the gasket inside between the socket and the housing.  If the lens is seated and not broken, the amount of moisture that enters should be insignificant and will burn off quickly from the heat of the light.  That's the theory, anyway.  The problem with that theory is that moisture can still get between the bulb and the socket, and in the case of the rear (non-running light) signals there is insufficient heat produced to dry them out.  My suggestion on this type of light is to coat the bulb with a heavier than normal amount of dielectric grease to form a seal right at the entrance to the socket.

internal bullet lights on a 5 month Yellow are all corroding on the reflector lense - washed and blown off so no water is free standing - but these are not sealed lenses and they look like chit on the inside - noticed when smoke where removed for same reason @bulb change - this is on all 4 lights- if MOCO did not want them to corrode they should have sealed the dang things - DUH - its only logical

One thing you can do after you have the MoCo replace the housings - put a very small bead of clear silicone sealer around the edge of the lens, leaving a small gap at the bottom to allow moisture to escape.  I did this on a set of bullets that I installed on my '99 Dyna.  The only problem is, when you need to remove the lens for bulb changes you may wind up breaking the lens.

I think I remember BLM777 saying he uses that same technique (silicone) to keep the moisture out.  Now, if we can figure a way to keep the moisture out of the electric horns so they will work everytime you need them.    [smiley=nixweiss.gif]   spyder

I had the same problem and it began to drive me crazy!  [smiley=nervous.gif]
I had the kuryakyn Panacea http://www.kuryakyn.com/lthd.asp?bn=harley&cn=Lighting lights on the back for about 15,000 miles with no problems so I decided to fish the system with the front. I got the dealer to order the new front housings and the kuryakyn smoke turn signals at put the system together right away. Put plenty of the dielectric grease in there and then as I snapped on the cover I remembered what a great seal those caps provided. http://www.kuryakyn.com/products.asp?bn=harley&ci=3014 The lights look great and have not had any problems.  [smiley=xyxthumbs.gif]
I think Mrs. We is heading down the same road, I gotta learn how to say "Two please," from now on!  Har! [smiley=beerchug.gif]

Has anyone tried putting a lightweight "O" ring around the lense and seal it off that way? [smiley=confused5.gif]

I have also put on the kuryakyn panacea leds on the turns signals front and back as well as the laydown tail light and love em.   So far they seem to stay nice and clean and put out a stonger light than stock that looks very clean.  JP [smiley=huepfenjump3.gif] [smiley=huepfenjump3.gif]

Does anyone remember someone posting a type of amber bulb that is not coated, but true amber that will not peel off?  I can't remember the brand name to go looking for them.   [smiley=nixweiss.gif]   spyder

The replacement is the NAPA True Amber.  It will be the same numerical code as the one that comes in the bike with the initials TA following it.  Won't peel, lasts twice as long and is roughly half the price of the HD bulbs which I found to have a life of about 60 days.

Spyder, any auto parts store will have something.  The nomenclature is nearly always an NA or TA after the normal part number.  Natural Amber or True Amber is what it stands for.  They've been around forever and come in all the longer life bulb variants on he market now as well.

wonder why the MoCo can't use them instead of the ones w/ the coating that peels off so readily?  [smiley=confused5.gif]    spyder
