That's very clean looking, too. Best looking modification I've seen done on these lights.

 

Correct. Dan

 

Not sure about the early ones but my 95 the fuse is right down by headlight on drivers side and can be easily removed.

 

This could be a learning moment for me, however I cannot think of a reason why converting to a #6411 Sylvania LED bulb with a 0.04 amp draw wouldn't be sufficiently negligible compared to the 0.83 amp draw of a #211 incandescent bulb, thereby having no need to install switches or remove fuses? The amp hour rating of batteries typically used on C4's, at least in the case of a 1994 LT1 is 63 amp hours. Using the formula 63 Amp Hours divided by 0.0.04 Amp Draw = 1,575 hours or 65 days to drain the battery to 0.0 volts. 2 LED bulbs would cut that time in half or 32 days.Using the same formula calculating the 0.83 draw of two #211 incandescent bulb, a fully charged battery would be dead 96 hours or a approximately 3 days. Back to the voltage drain of the 0.04 LED bulb, considering a fully charged 63 amp hour battery is considered effectively "dead" at 11.9 volts, there's a 0.9 voltage "window" that a fully charged battery has before one could expect the battery doesn't have enough voltage to activate the starter motor. Following an online formula to calculate how long it would take to drain a battery charged at 12.8 volts to 12 volts with both LED bulbs are lit, it would take approximately 8 days for battery voltage to drop to 12 volts; two incandescent bulbs this drain to 12 volts would take less than 1.5 days.

 

Made a believer of me. I just looked up a 6411 bulb, and it looks like all you need do is take out the old bulbs and put the news
in their place. Be nice to get away from all the heat those old bulbs generate too. I'd guess they're not quite as bright as the old bulbs...that and the cost of the new bulbs would be all the downside. LED's likely last almost forever too. TY for your info. I still don't understand what Benjamin Franklin learned from that key attached to his kite line. (I understand so little of electronics, it's nice having it explained.) Doug K.

 

I just read of some bulbs called festoon, that appear right-sized, and advertised as .5 watt, 12v only, and are brighter than T-3 halogens, which is what I guess our original bulbs are.They're not advertised as a 6411. Are these bulbs, sold by a company called PLT an acceptable superior replacement?

 

@Dougk50 I'm not a genius when it comes to electrical. My curiosity led me to the internet to learn what i could and i found the formula to figure voltage draining with different amperage bulbs.You mention "festoon" bulbs. Could you post a link to what you found?

 

I'm so technically challenged....all i know is copy and paste and that didn't work. It's the first thing that came up when I did a search. Sorry Steve and any others. Sounds like you had a fair amount of patience and fortitude to understand all that electrical info. TY Doug K.
