Noob question: I have a Clairtone 7978 with nonfunctioning tuner display bulbs. I have seen Fatdog's post from several years ago on the 2 led customization of a rising-2015. Slightly intimidated as a completly unskilled rookie I started to look for bulbs. I found several options which I would like your advice on and wondering if the approach has changed since the original mod.


1. 6V 100 ma Axial lead bulbs


2. 8V 200 ma Axial lead bulbs


3. Warm White 3 LED Axial 8 VDC Replacement Lamp 5-Pack (white or green)


4. The 2 standard LED mod seen previously.

Any thoughts, recent experience or suggestions?


2 LED Rising lighting mod reference.

I have recent experience (Sony FH-7 replaced with LEDs with thanks to RockE's guide)




Am a noob too, do you have a photo of the 7978 bulb and circuit board it is on?
