dash lights
I've ready that the bulbs in the dash, on a C4 can be replaced
with 194 bulbs and appropriate bulb holders. good side is the bulbs are cheaper, and easier to get but the down side is the dash is dimmer. has anyone, replaced the bulb holders, and used those high intensity LED replacement 194 bulbs ? they shouldn't burn out ( thats a plus ), they are a bit pricey ( but worth it I would think ) Question is the brightness, in side markers they do rather well, can hardly tell them from a bulb. But not sure how they'd do in the dash. has anyone tried this ? |

Since I haven't seen them, I can't truly comment. However, most LEDs I have
seen are more directional in how they shine their light. The light in a dash is more about spreading around to cover the instruments. As long as the light gets directed over the instruments, I guess that would work. Another issue would be current. If their current requirements are higher than the existing bulbs, you might have to worry about wiring issues. This is an issue with '63 Corvettes. They were designed for one bulb, the '64 up for the 1157 which is brighter but with more current. So there is a warning to not use them in the taillights of '63s. I don't know anyone who has ever had a problem, however, there was a concern by Chevrolet years ago. I don't think it is likely, but I guess on an old wiring harness, you could heat the dash wires up and have a problem.

LED's draw much less current for the same amount of light, mainly because they
don't get hot, also because they don't use the whole spectrum of visible light (not sure what the deal is with white ones, but I bet they have a different 'look' than incandescent.)

I don't know anyone who has ever > had a problem, however, there was a concern by Chevrolet years ago. LED's use far LESS current, I've used them in 'idiot lights' and they work real well. Only problem is you have to either get a 'white light' LED or match the color of the LED to the filter on the indicator. Taking the dash out is a pain, so if I can replace the bulb, with something that doesn't burn out .... all the better. They do make 'diffuesed' LED's that aren't as directional http://superbrightleds.com/mini-wedge.html again my concern is 'brightness'. the halogens that are stock will be hard to beat. |

While the LEDs run cooler (less long term damage to the circuit boards & sockets) they don't play well when dimming is needed. The incandescents & halogens dim by varying the voltage -- most successful dimming schemes for LEDs use a square wave and vary the duty cycle. For now, the dimming modules for LEDs are really bulky (gadgets that fit in the base of a table lamp etc.) Electronics tend to shrink with time -- try again in a couple of years. -- pj |
