Radar detector screams Laser everytime I use the Horn.

Radar detector: Escort Passport 8500 x50
2005 Lotus Elise.

Anyone experience this?
Thanks.

Common, there's a fix for it, but it's vehicle specific...and I'm not kidding. I sent mine in when I had my STi, and they fixed it...for the STi, so when I installed my Supertones the damn LASER would go off, and now with the Exige it goes off as well. Stupidity.

Same Detector here. Laser used to go off when I would adjust the power mirrors.

check the voltage at detector while honking the horn & see if there's a drop.

If so, p/u power from another source.

Same here. I have the 8500 X50 (blue). I was told it has something to do with certain horn relays causing a "flash" that mimics a laser burst, and if the relay is not shielded somehow from proximity to the detector from its location (because our cars are mid engine, it's not blocked by a standard firewall), that this is "normal". IOW - TADTS

It's annoying, but not harmful - I don't think.

It is caused by a voltage drop. Move the power to a new location. Pull it from the small fuse box under the dash.

Yes, just what I said 4 posts earlier. Not rocket surgery.

Yes...I know you said it earlier, but sometimes we have to say it a few times till it sinks in......

I don't agree with the voltage drop. My STi had the issue with the horn, I sent the Passport to Escort and got it fixed. When I installed my Supertones, it returned. However, during some acceleration pulls it would do it as well, lights on, or lights off, stereo on, or stereo off, etc. I think it's some sort of frequency issue.

I am not going to say that I know everthing about radar dectector installation.
Hell...I might be wrong.


Easy to check though...just power up the dectector right from a jumper wire to the battery..both ground and positive....then honk the horn.

This jives with what I said in the other thread that was referenced and what I think is probably going on here:

Me said:
My friend has the same problem with his X50 every time he accelerates. It is not an isolated incident. You have to send it to Escort for repair. Check this thread: Escort X50 Radar Detector Issues... - evolutionm.net
FWIW, I had my BEL hardwired in the car and never once had a problem and I had a Stebel Nautilus. So I don't think it's voltage drop either; still, I guess it's worth a shot. I'd probably take a reading with a meter at the detector end, if that's possible.
