indicator flash speed

ghetto3 · 25-07-2012, 08:37 PM

Hey just a quick heads up, if youve changed to LED indicator bulbs and have the strobe flash thing happening, the correct resistor value is 220k (#rr2830) available from jaycar. Just rip the flasher module out from under dash, above right of the foot pedals, look for resistor labelled R1 and replace! Is this worth a how to? i could actually contribute to AGT for once...

Edit: this will get you closer to a standard flash rate.

Edit2: 220k carbon 5% 1watt will work too.

do it. one of the reasons why i haven't switched the indicators to led. please do a how to.

BG1.8sp · 25-07-2012, 08:46 PM

Well some people say that they want to go LED globes because they use less energy... This defeats the purpose....
If you want to do it properly... Get a new Timer relay and adjust it to however you want it. You get the energy saving of LED and the look/ brightness

ghetto3 · 25-07-2012, 08:49 PM

Will do, ive got a heap of low res photos but i might try and mock up a few macro shots. It is quite easy really.

Clean_Cookie · 25-07-2012, 08:59 PM

so each bulb is 5W? so x3 = 15W = 1.08A

swap to led. put 0.5w led in, = 1.5W @ 13.8v eg = 0.1A approx = 138 ohms. add 300 resistor = 438 ohms = 0.03A = alot less?

what have I screwed up? yes the resistor is wasting power, but its so small due to the low inital load?

edit. im an idiot. the resistor used is a 330K, if that was in the circuit directly, vd over it would be huge (I=v/r 13.8v/330000 = stupid small) (and nothing would feed the led's) so it clearly doesnt just connect in series with the bulbs.

so your saying there's an adjustable flasher unit? AZZ why was this never brourght up in our convos about our entire led conversion???

project.r.racing · 25-07-2012, 09:00 PM

2x 21w globes and 1x 5w globe, does this change anything?

BG1.8sp · 25-07-2012, 09:01 PM

Lol I thought you knew this but cbfed.
Will get back to you eventually with a part number

^^^ that's an example

is it actually a smaller rated relay or dose it just have a resistor in it? because then it's just the same as adding resistors to the curcuit, meaning the only gain id the superior amber flash still

Clean_Cookie · 25-07-2012, 09:09 PM

technically yes. Ive got 5 dead flasher units here. dont ask...

47W in series @ 13.8V = 3.4A wow, thats actually quite high. maybe I will do a swap too. (plus more) indicators can be controlled via my computer anyway, teeheehee. oh the fun I can have.

edit: for those not familiar with electronics and how it works. the higher the resistance in a circuit, the less current can flow. a resistor in a circuit will have a voltage drop over it (i.e you meansure before the resistor with one lead and the other directly after and you will come up with a voltage. all drops over the circuit will add up to the supply voltage.

but, when you put resistors (or anything) in a circuit in series like we are doing with these bulbs, all the current has to flow through every resistor/bulb to get back to the start/end. so by adding a resistor, you must calculate total resistance, work out max current flow and then rate the ressistor appropriately. with a 330K resistor as stated above, will be a minute amount of current so only a 1/4W resistor would be required. if you were however to add a 10ohm resistor into a 12v circuit on its own, it would pull 1.2A through it and require a large heat sink! hope this makes a little sense.

also think about a bulb as a resistor, yes when its hot it changes its value but essentially its the same thing. (i,e a 21W bulb @ 13.8v would have a hot resistance of approx 9.2 ohms)

Rupewrecht · 25-07-2012, 09:11 PM

I just used some of these for my rear indicators

Clean_Cookie · 25-07-2012, 09:20 PM

dan this is not an effective solution for power saving! it works perfectly, but adds the total up to what a stock bulb would be and thus use exactly the same amount of power. added bonus is more light I guess... the ghetto way seems the most intelligent as it does what the thing aaron seems to have linked, like the flasher relay has a timer in built and this slows the charging of a capacitor or something.

BG1.8sp · 25-07-2012, 09:35 PM

Except the timer delay relay doesnt increase the resistance. Well not nearly as much as the 330k resistor. So you get the best of both.
But yeah for a quick job that will get the lights to work normally and look good. Don't bother with that crap I posted... Personally I wouldn't even do it myself. Really not going to make a difference anyway.

Looking to save power with LED globes is a waste... Especially of you have Amps and subs in your boot

lol. ... LOOKING AT YOU ANDREW!!!!

Clean_Cookie · 25-07-2012, 09:43 PM

what I was trying to say is that the 330K resistor will SAVE power if wired in series with the lights. the higher the resistance the less current can flow. it will be in the timing circuit though and will most likely be used to drain/charge a capacitor and the rate at which it does so is how fast it blinks on and off.

haha that's the reason why i have a optima and evry light in my car is L.E.D bar the head light's which are now 35w (hehehehe) and the one's behine the ac controler unit, and the indicators lol, trying to save as much power so with the sound sytem it's not completely just r*ping my altenator lol

righto now hit me with your "your an idiot" lol

BG1.8sp · 25-07-2012, 09:48 PM

Lol well that explination makes more sense...

Still my point stands.... What's the use in going to all that effort to make your lights use less power when your multiple amps, speakers and subs are doing a damn good job at sucking all the juice they can get...

Stick to the original (first) post!
It's the easiest... Quickest... And most effective. Oh and cheapest.

Lol.... If you have to go to that length to change every light to use less power... You really need to consider upgrading your alternator!

BG1.8sp · 25-07-2012, 09:53 PM

Also are you running caps?? Because that takes a bit of load off

yer but that costs money lol, and takes valuable power away from the engine
