My RX-300 has no high-beams / DRL's.

I hear a relay click, the high-beam dash indicator comes on and the fog lights switch off. I changed both lamps. Wiring and sockets were clean.

What's my next step ?? (I'm a retired EE but don't have a clue how this is wired.)

Thanks.

EE is always an EE retired or not

I too have not figured out just how the drl's work for sure. The high beam fillament glow at 1/2 brightness. My guess is that for drl, the lamps make a series connection and for regular operation they are in parallel [all done by relays]. For this theory to hold, the bulbs must have a mechanism to isolate from chasis (gnd). How???

Sorry for a half baked answer. Take it for its worth.

Yes, the DRL are in series and it is done with relays (several) to take care of the ground issue. The diagrams are available in the books. Here is what you need.

One EE to another....

and since we can't make out the diag. send me a private e-mail and I'll forward the larger file with readable detail.

I have the same problem. When or if you figure out the problem please let us know. Thank you.

Have you guys checked the fuse??

I'm not an EE, just a handyman around the house.
