FLASHER UNIT REPLACEMENT

Indicators been slow for a while now stopped, upon investigation a cheap and nasty flasher unit had been fitted. As a temp fix I have put the inferior unit in the bin and put the hazard OE Lucas fitment (dated Dec 1976!) on the indicator circuit and all is well again. Reading the origional HAZARD unit Lucas part no 35053, I understand its modern day Lucas part number replacement is SFB 130. Obviously this fitment is used as it is capeable of powering 4 bulbs instead of 2. I believe the origional Lucas part number for the FLASHER unit to be 35048, its Lucas modern equivalent now being SFB114. The difference been this unit will only power 2 bulbs at once.

Question. As I want to use my p6 to pull the caravan next year should I buy the 4 bulb unit to use on the indicator circuit and if so what are you supposed to do if you need to operate your hazards with the caravan attached, surely you need a flasher unit that can cope with 6 bulbs flashing at once? What is the solution to this?

Thanks in advance for any comments

Amongst a number of possible answers, one very simple solution is to fit an LED flasher unit. These are designed for use with either LEDs or standard bulbs, and do not use the current draw to dictate the flash rate (hence why you can use LED clusters as well as incandescent bulbs), thus allowing you to power 4 or 6 bulbs without a change in flash rate. They are not prone to wearing out either, so it's more of a long term solution. The only possible down side is that you wouldn't be able to tell from inside the car when a bulb had gone, as the flash rate would remain unchanged.

This is about the only 2-pin configuration I could find, so I fitted 2 of these to my car- pricey, but fit-and-forget.

I wondered if anyone had used those LED flasher from Aceparts, did you cut the bullets off and add spade connectors Michael?

There are lots of 2pin flasher relays with blade connectors listed on eBay but they're aimed at motorbikes although I can't see difference it would make if they're still 12v?

Yes, but rather than fitting spades, I just jointed the wires together with connector blocks. A lot less messing and just as easy to remove. The extra lengths of wires also gave a lot more free play to locate the units somewhere sensible where they won't fall down into the glove box as you open it!
 
Cheers Mike, this looks like the way forward. I am at pains to come away from origionality however as Lucas replacements are £10 each inc postage I dont think these LED units are too pricey at all! especially as they wont wear out, and also relieve me of the problem of wiring up the appropiate regulator for the hazards etc. PURCHASE MADE!!

Thanks for link triffic!

I can understand what you mean, but at £20 for something that is just going to wear out anyway is false economy in anyone's book. I have a receipt in my car's history for new relays in 2008 - between then and 6 months ago my car covered about 2500 miles, and both the flashers were knacekered in that time! Don't know if that's a slight short in my system, but the LED flashers have given no trouble at all.
