Locost turn signal buzzer
Xtreme Kermit - 15/8/09 at 08:21 PM

Fed up with leaving the indicators on and not spotting the flashing light?

Well I fitted a locost buzzer during the week.

I used one maplin 12v buzzer, two diodes capable of taking the buzzer current (100ma), soldering iron, piggy back spades, some heatshrink and servo tape.

Connected the negative on the buzzer to earth, the positive to the ends of both diodes with solder blob. Fit heatshrink over bare wires. Fit piggy back spades to the other ends of the diodes and use more heatshrink to cover the bare wires.

Use the piggy back spades to tap into both wires on the back of the indicator warning light. Servo tape the buzzer to the back of the dash.

Voila - one cheap indicator warning buzzer that can be heard up to about 60mph.

Here is the buzzer I used

Nice one matey, don't suppose you have the maplin codes of the diodes as well do you, just so I get the right stuff.

Cheers

Just out of curiosity, why couldn't the black gone to earth and the red go to the dash indicator bulb?

Cheers

Generally the W/L is wired between the NS circuit and the OS circuit. The W/L bulb grounds through the non-active indicator bulbs; it's not directly grounded.

for £2 each, i guess it wouldn't break the bank to just fit one for each side. saves worrwing about diodes and stuff

Blake, will that not put more load on the circuit, making the flash slower?

for a buzzer i just bought a flasher relay with a buzzer off ebay for cheap, works a treat

Originally I had a buzzer, 'cos I kept leaving my indicator on. After a while it drove me nuts and really got on my nerves.

It was replaced by a Bright-6 light unit and a proper self-cancelling unit for my Sierra steering column.

only one way to find out

nah, i don't think it would though, because the way he's done it, you turn left and the indicators have a buzzer in the circuit, you turn right and theres a buzzer in that circuit.
having one on each won't have any other effect on it. and i think flasher relays only change speed when they get below a certain load. i don't think adding more will make it flash slower

re: 2 buzzers - chance are they are not madeto precise tolerance so would have different tones so you would know which side is indicating.

re: flash rate, maplins say 100 mA but I reckon it would be less; compare that to two filament bulbs, 21 W each or 4 A total so approx 2 % difference - nothing to worry about.

Ahh my bad, not being picky blake! Its just that its exactly what I would do and it usually goes wrong lol
