I built my RV using a B&C SSF-1 wig wag. Wired  it per Aeroelectric recommendations and it worked fine. 

  

 I changed one light to a Xenon lamp using a Philips  Xen Drive XLD912 Standard power supply. This does not load the SSF-1 flasher as  required so my wig wag no longer works. I would like to keep the Xenon on one  side and the incandescent lamp on the other. I would be happy with flashing one  lamp if not both.

  

 Any solutions?

Dick,



If you truly would be satisfied with flashing one lamp and if you have enough 

power budget for the additional current the Xenon lamp requires and if you don't 

mind a little re-wiring, you could substitute a power resistor for the 

incandescent lamp that was removed.  The resistor will keep the flasher happy. 

Think of it as a non-illuminating lamp 



Assuming you're using a 55W lamp at 14V, you would need 3.6 ohms capable of 

dissipating 55 watts half of the time (50% duty cycle).  A couple of 10-ohm, 

20-watt resistors in parallel should be close enough to fool the flasher and if 

not, add a third one.  FYI, those resistors will get very hot; don't put then in 

your lighting switch panel.



My wig-wag uses an electro-mechanical flasher too and this is what I plan to do 

when I upgrade my lights unless I spring for a new (solid-state) flasher.  But 

that's not going to happen until after the airplane's flying <g>.

     If your new HID lamp/pwr-supply combo will tolerate

     flashing, then you can also consider adding some dummy-load

     resistance in parallel with the wires to the HID

     power supply.



     We did a patch to the B&C Wig-Wag instructions to

     accommodate LED lamps, same fix should work with your

     HID too.

     There's a solid state wig-wag controller development

     program under way right now

     . . . parts I had on order to finish the proof of concept

     boards spiraled down the USPS black hole when an error

     in zip code left my parts looking for a Medicine Lodge

     address . . . in spite of the fact that the printed address

     was correct. Lessons learned, USPS mailed with a confirmation

     track is delivered by USPS bar code . . . Address mail to

     me at 67104-0130 as the ONLY address and it will get here.

     Have an error in the zip code then it doesn't matter what

     the rest of the address says . . . anywho, that all got

     sorted out and the parts should be here Tuesday.



     In the mean time, you could put 75 ohms across the HID

     lamp supply . . . I think the B&C electronic flasher

     will get happy again.
