The warning indicators are much easier to see during the day, which is important, since my 16-year old daughter will start driving the Alfa this summer.

Whether you go LED or bulb, increasing the brightness of the instruments is definitely worthwhile.
That is a good tip about the direct fit higher output Silvana bulbs Shakey!

Looks like your stable is full. Regretfully mine too: 1925 RR Drop Head Doctor's Coupe, 1959 AH, 1967 OTS E-Type, 1968 Tr250, 1979 Rx7 and 1989 Graduate. What was I thinking? Herb

Two questions 1) Are the LEDs dimmable? 2) You said they are polarized. How do you know if you have them in correctly for the ones that aren't supposed to be on? Oil level, etc.?

It doesn't say on the web page, but generally the automotive LED bulbs are not dimmable, no.

That being said, the ones listed are for the warning lights, so it's not like you'd want to dim them anyway. They're not under the dimmer circuit.

I found a less-expensive source for the 2723 bulbs. Rather than buy a pack of 2 for $4.99 at the auto parts store, you can buy a box of 10 for $4.97; about 50¢ each:

2723 bulbs at 1000Bulbs.com

It certainly makes the economics of upgrading more attractive. I've replaced every bulb in my instrument cluster.

As an update to this thread, I've been running the 2723 bulbs for several months now, with no adverse affects.

Being LED's they generate next to no heat. One of the better safety upgrades I made in my S3.
Great suggestion. I just installed these. The only real issue I encountered is they don't seat really well (tightly) and I'd hate to have to remove the pod whenever one shook loose. My compromise was I just replaced the few that illuminate the dials. The warning lamps are fine with the stock bulbs. I'm going to drop tiny bit of glue on each LED to keep them from shaking loose.

Looks like they are discontinued.
