Went to several websites trying to find the exact fit bulb with neo wedge base. Found the exact bulb at JKL components . They were part # DNW1-EW33/30MM and were only $2.50 a pc. The only thing was that you had to purchase a lot of 10. So with shipping it was $32. Opted to replace the bulb with LEDs purchased from Amazon. The bulbs I purchased already had the resistance diodes attached and insulated. Just had to drill out the old base to allow the diode to thread through. The bulbs are polarized so if it doesn't light up just remove and reinsert the base 180 degrees, will light right up.
