LED turn signals with resistor, same current draw as regular bulb?
If I change over to LED running lights and turn signal bulbs I am likely to get the "fast" flashing turn signals (due to the low power consumption of the LED bulbs). The fix seems to be wiring a resistor into each bulb. If I do that, am I then still drawing the same power I was with the incandescent bulbs?
Only reason I could see to do it (if the power draw is the same) is for the longer life of the LED bulbs (hate squeezing my hands in there to change the turn signals when the bulb goes :-) ).

yes you are guranteed to get the fast flash if you change the front DRLs to LEDs.
a resistor will not prevent the fast flash in the front, they will burn out.
the only fix, other than to replace or rewire the flasher, is to add the OEM bulb back in the series.
do a search under my name for a thread on how i did it.

I like the fast flash. and am keeping it.
Even the soccer milf see im turning and let me IN.
In more ways than one.

I may lust pop led bulbs in the front and see if I can use it with the fast flashing. This will probably burn the other incandescent bulbs left (the ones in the tail lights) out faster, but those should be easier to change :-) (not ready to switch to the led tail lights yet).
Thanks for the info, I did remember reading your post but didnt bookmark or have your name :-)

My bulbs last about 9 years WHY do yours burn out so fast
I JUST replaced my FIRST brake/tail lamp about 3 months ago on my 98 C5. Another original bulb in the rear went about a month later. So I replaced the other 2 also. Fronts are a PITA to get to and are holding up just fine. I guess you get exhausted doing this job once every 9 years. Or does your car get struck by lightning often? BIGHANK

I also have a 2001 and when the first time the turnlight (DLR)went out
I repleace them. Now it almost every 6 month one or the other is going out. I notice they are getting wet from where the light is plug in. Heat
has change something.
I have a question will the LED making the Flashing light rapid flash
will this hurt the Flasher?

burned out lights
Well at least my 98 C5 has ONE good set of parts. The front turn signal/running/parking lamps. I'm not changing ANYTHING till it FAILS.
My father's adage of "LEAVE IT ALONE" until it breaks beats tweaking and sometimes ruining things which if left alone function very well.
When I tried to replace the headlamp bulbs several years ago for glitzier ones the combination of my large hands and the easily bendable prongs on the headlamp meant I had to totally disassemble both headlight assemblies and straghten the retaining prongs with needle nose pliers. Thank God I spent $160 for the Helm manuals so I could do this job without causing further damage.
Some if these "enhancements" are just busy work. BIGHANK

If the resistors burn out, it means that you used a resistor that is rated too low. The bulbs that you are replacing are rated at 27 watts if I remember correctly. The resistors should be rated at least the same. I used 6 ohm 30 watt resistors in my LED tailights and all is fine. The resistors will get hot so be careful where you place them. Use a higher wattage resistor for more safety.

you can get away with using them on the tails because they're not on all the time, but for the front, everything i've read has said resistors don't work.

If you have the LED specs then you can use this formula
R = (VS - VL) / I. R = resistor value in ohms ( ). VS = supply voltage. VL = LED voltage (2V, or 4V for blue and white LEDs). I = LED current in amps (A)

You only need to find the correct wattage/resistance resistor. Too small of wattage will burn up. The problem is getting the LED bulb specs.
