I have finally found the LEDs I want to replace the halogen high beam bulbs. Will they light with the voltage that my 2nd Gen (2014) TSX SE puts out for the running lights to these sockets? (I want to keep my running lights working.) Will they be too bright as DRLs?

Thanks!

You may be right. Apparently, adding a resistive decoder between each LED bulb and the car's wiring will keep the dash error for DRL from lighting. However, the brightness of the two LED bulbs with the lower voltage the car uses for the DRL function (actually putting the two bulbs in series, I have read) seems difficult to predict. They may light at full intensity, not light, or light at the desired reduced brightness. I have asked this question of three vendors of headlight LEDs and I am hoping for a straight answer.

Thanks for your response.

Looking at various forums shows me that most people who put in LEDs for headlights want to make their cars stand out with fairly blue high and low beams and fog lights as well. Almost all headlight vendors here, responding to the US market, do not advertise LED bulbs at anything under 6000K and many claim to offer them up to 10,000K LEDs. (Real light at 10,000K is bright blue. See https://www.google.com/imgres?imgurl...10B-MQ9QEIRDAA )

I just want to improve the brightness of my high beams, have them match the color of my TSX's HID low beams, 4300K, avoid tickets, and keep the DRLs going. Maybe buying some 4000K, short-lived, high-end Philips halogen bulbs is easiest.

THe DRL circuit usually runs at 6V or roughly half of full voltage so as to run dimmer. LEDs don't have that kind of functionality.
