Camp, I had the same issue and was informed by a rep at The Retrofit Source that the VFR uses 7440, not 7443. From them: "The reason why the switchback bulbs don't work is because you socket is actually a 7440 not a 7443. All 7443 plugs have four contacts, two power and two grounds which control the running light and turn signal function. Your two pin socket just controls the turn signal function power/ground. As you can see in the Osram OEM bulb guide here: http://www.philipsautolighting.com/bulb-lookup.php?make=67&model=3334&year=2007&trim=NULL. " I found these on Amazon: https://www.amazon.com/gp/product/B008C9DINC/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1 And they work great. I'm very happy with the results.
