I have a friend who has static interference in his caravan radio when the LED bed reading lights are turned on, this has only just started as the lights have been in for a couple of years it has him mystified.
Has any one previously experienced this and what was you rectification method.

Hi Jim, yes static interference from LED lighting can have an effect radio performance, but the pros of LED lights far outway the cons. If it is too big a problem suggest they get a small hand size transister, cost around $20. Good value, good reception, good easy to handle size, & good battey life.

Hi Jim ..
Its probably of no benefit to you, but I operate a HF Radio as I travel. About 18 months ago I replaced most of my (internal) Halogen lights with LED's so that I might benefit from the low power consumption ..
However, when I transmit on the radio now, the LED's (not switched on) will light up like Christmas trees ..
If he's getting interference from the LED's, then I can only think it may be an older style radio that may be more susceptible to interference .. or .. ask him to just check the switching arrangement for the LED light. It may not be seating properly where inserted or when switched on .. a LED can still light up because it can 'arc' across a dirty connection .. and 'arcing' can certainly cause interference.
Try cleaning the connection .. ensure the LED is firmly seated and failing this, ask him to try another LED in its place ..
about all I can suggest Jim ..
cheers
Jon

Hi,
Led lights have a power adaptor built into them to take the 12 volts and convert it to the correct power to light the led.
Depending on the quality of these internal adaptors it is possible for them to generate electrical noise that interferes with radios that are not isolated from this noise.
Like has already been suggested good quality LED replacements are usally but not always ok, and usually cheaper than trying different radios.
Cheers,
Nichol

If nothing else has changed, this often indicates some sort of failure taking place in the lamp or lamps. Is it all the lamps or just one of them causing the problem?

I'm not familiar with the internal workings of these super-bright led fittings but maybe some of them use some form of switch-mode type voltage/current regulation that can generate RF interference? Their wide input voltage range (8 - 30 volts) alludes to this possibilty.
I recently installed a 30 led outside (weatherprof) strip light that does not cause any radio interference.
I had an interference problem with some 12v fluoro fittings that I overcame by installing a filter in the light fitting.

Hi Terry
Thanks For your advice, I think he wants to keep the radio as the interference has only just started.
But I will forward your suggestion.

Hi Jonathan.
The radio is about 3 years old and the lights have been in for a couple of years.
I will forward your advice on checking the cleaning of the switching.

Hi Nichol.
The led's are good quality as the were installed when he had the solar installed.

Hi PeterD
The lamps aren't very old and it is happening in both off them.

Hi Jim
I'm not sure if a filter can be installed on the led's as can be on a fluoro, it has been suggested that he install ferrits on the wiring to the lights.
