There is a device called bright-box if you just want to buy . Geno's has them.
Others have done it with relays for less money.
I have the DRL"S like you and I'm still not 100% happy with my 2"nd bright-nox. My low beams flicker during the day. I'm going to run for a week or so and see how it act's. Then I will talk to JOEL again,their customer service is very good and they stand behind their product.
