Resolved HELP! - 1992 5.0 Canadian with DRL - need electrical schematic drawing

[92StangGirl]

I'm new to this forum and have no idea how to use it, but I'll try.

I just had new LED headlights installed in place of original headlights which were quite dim. But now my interior dash high beam signal doesn't work when the car is running. All the lights work but just not the high beam interior blue light.

I bought my 1992 new in Canada and am now told that because Canadian Mustangs had to have DRL module, that may be the problem. Can anyone help me to figure out how to get the dash high beam indicator to work? Can anyone send me the Canadian version of the electrical system that I ca give the automotive guys that put the new lights in. Only advice they gave is to gorget about the blue light interior indicator, which I don't want to do without if I don't have to.

ANY help will be most appreciated.

LEDs use significantly less power than incandescent bulbs to produce the same amount of light, which can sometimes be too low for a car's dashboard system to recognize properly.

Adding external Resistors usually fixes it

Thank you so much for your prompt reply, Mad Dude. I'll convey that too my repair guy and hopefully he gets it and will fix accordingly. I'll report back how that works out.

Oops, I meant thanks "RaggedGT" (sorry, new to this site)!

Also, I'm trying to keep the car as close to original as possible. So I'm wondering if it would have been better to just put in better/brighter halogen versus LED lights? And, if so, would that avoid the dashboard high beam signal issue?

Do LEDs work properly in these housings? Like how HIDs blind people when not in the correct housings?

Maybe you can remove the DRL module all together? I believe it's inside the driver side fender.

I think either the resistor or switch back to halogens is the fix. Don't forget DRL is high beam with half the power applied. When you have LEDs they don't use enough power (compared to halogens) so the rest of the high beam circuit uses it - the high beam indicator. The resistor should consume enough of the excess power to keep the indicator light off.

A big thank you to everyone who has replied to this HELP post! So appreciated!! I haven't yet had the chance to convey the helpful advice to my automotive guys but will report back on decisions and results!

Solved! Removed the LEDs and just had new halogens put in. Works like a dream again now. Thanks for the tips. Was an easy fix!!
