Could be the light switch is bad , but that would be just guessing ? And you don't want to replace parts form a guess posted on here !
The way to find the problem is with electrical testing , using a volt meter , wiring diagrams an leaning how to do automotive electrical testing , how to read an use wiring diagrams etc.. Testing B+ voltage to the headlamps an the ground circuit using voltage drop testing . That is if you want it fixed right .

There should be a relay under the hood or in the fuse box for day time running lights. Most of them are labeled.

I had the "service vehicle soon" light come twice with in 1 year. First the heald light bulbs were gone. Replaced the head light bulbs and after 2 starts the "service vehicle soon" light was gone.
The second time the DRL - #194 amber bulbs were gone. Replaced these and the "service vehicle soon" light was gone after 2 starts. The DRLs are housed in the headlamp housing, the tiny bulbs beside the head light.

perhaps i missed something here... lowbeams and daytime lights are about the same.... be that as it may... the merely obvious thing is that the low beams are burnt out.... next thing would be that the relay for the day time lights could be defective... it's often mounted on the firewall.

The blinking light is telling you that you have a headlight out, if you look the service light should be coming on when the light stops blinking.
Replace the head light and all should be fine.
SOURCE: Can't shift out of park, no brake lights/turn signals
Had same problem. Our trailer electric wiring harness had a bare wire that shorted when it touched the meatl trailer hitch. This blew a fuse. The fuse that it blew also control the transmission lock out thus not allowing you to shift out of park. I believe it is a 15 amp fuse. Of all the spare fuses in the van there is no 15 amp available. I took the fuse for the heated mirrors and swapped it with the blown fuse. Problem fixed but no heat for the mirrors. Better that than no tranny.
