You would be surprised how much brighter the dash can be just by putting aluminum foil around the inside of the Gauge Cluster box as a reflector.

Guys,

 

This tread was the ticket. I made copies of everything and will be ordering bulbs for the 521 and the Roadster. Pretty cool, thanks.

And the pics were right on. It let us noobs see what you are talking about.

Thought I'd ad some standard bulb info for the 74, 161, and 194 wedge series:

 

#74 - 1 watt - 14 volt - 0.8 x 0.2 - T1.75 - Wedge (W2 1x9.5d) Base

#74 - 1.4 watt - .1 amp - 14 volt - 0.8 x 0.2 - T1.75 - Sub-Min Wedge (W2.1x4.9d) Base

#74LED - .25 watt - .014 amp - 12 volt - 0.75 x 0.2 - T1.75 - Sub-Min Wedge (W2.1x4.9d) Base

Note:  Don't know why 2 different #74's have different Bases:  9.5d -v- 4.9d
 

#161 - 2.66 watt - .19 amp - 14 volt - 1.1 x 0.4 - T3.25 - Miniature Wedge (W2.1x9.5d) Base

#161 - 3 watt - 14 volt - 1.1 x 0.4 - T3.25 - Wedge (W2 1x9.5d) Base

 

#194 - 3.78 watt - .27 amp - 14 volt - 1.1 x 0.4 - T3.25 - Miniature Wedge (W2.1x9.5d) Base

#194LED - .6 watt - .043 amp - 1.1 x 0.4 - 12 volt - T3.25 - Miniature Wedge (W2.1x9.5d) Base

 

Parts manual shows:  26261-89902 which is a 1.7 watt bulb  where the datsun1200 folks state: a  2.7 watt Type 161 is often specified by aftermarket   (Awesome bulb dissertation at datsun1200)

 

The implications of this are huge if you still have the OE bulbs:  a run of the mill 161 would be a significant improvement, not to mention a 194

 

Then the BIG PROBLEM:  What color... what color.... what color...  (I suppose Green would be OE)

I did the led upgrade on my 521 that we are making a daily for my son. We went with red. It looks great so far. I have not got it on the road yet so I don't know if they are too bright at night.

I ran into one issue with the IGN light. It was not working. We had installed as internally regulated alternator from a pathfinder. It requires 12v switched power to the "L" connection on the alt. I found that the 12v go through the light and then to the alternator via a White w red tracker wire. The Led light I had would not the the voltage through Which wouldn't
Illuminate the IGN light nor excite the field. I had no charge from the alternator until I replaced the LED with a regular bulb.

Mutt Dad had this same issue on his BMW motorcycle at one time. Thankfully i remembered this and was able to figure it out.

Just thought it may help someone with a similar issue.

Mine is a 1972 521. For reference.

Cheers
