Go with e new LED replacement

John D · 2K+ Club

194 = 3.8w, 2cp
184 = 3.4w, 1cp
168 = 4.9w, 3cp

All are the same T3-1/4 bayonet base, and physical size difference isn't enough to worry about.

What about tempurature, John ?? The 194's get hot enough as it is. Would the 168 start melting plastic holders ??

I agree with Tom. If you can find an LED replacement, go with that.

Heat is a problem, especially when GM changed from stamped tin to plastic housings. A 168 would probably be too much.

I haven't kept up with the LED replacement bulbs, but I've heard/read they have improved the "dim-ability". Problem with an LED is they have a specific voltage range where they work - they are a solid state device. Too low they simply won't turn on. Too high and they'll fry. Incandescent bulbs are analog and infinitely "dim-able".
