Do NOT install the new lines until you've resolved the problem! The last thing you want to do is add a new variable to the problem.
Yes, be 100% sure the battery is 100% charged. Sitting, overnight (it matters), on a bench or completely disconnected in the bike, the rest voltage is 12.8V. Anything below 12.7 means the battery isn't charged, If you can't get there, have the battery load tested. Low voltage can give the two-red lights blinking problem. BTDT
Since you didn't report loss of braking (you'll know!), I'd look at the battery, first, and then the ABS sensors. It's possible that one or both are no longer at the correct distance from the rings. BTDT See the Clymer manual for adjusting the sensor gap.
Assuming the brake fluid is up to the marks on the front and rear reservoirs (if not, why not?), here's an off-the-wall possibility. The lights flash, and the brakes are 100%. If the level sensor switch for either reservoir says the fluid's low... flashing lights. BTDT, too. The rear sensor went out in my KRS. Finding a spare was ...um... interesting.
If all of the above doesn't change things, all that's left is to bleed the system and hope for the best. Before starting the job, a small question: when was the last time the brake fluid was replaced? Brake fluid likes to absorb moisture and the only "cure" is to flush the system with new fluid.
IMNSHO, unless you're familiar with brake systems, once you've done the easy stuff, time to let the pros at the job. It's possible the ABS controller has failed or is going, something is leaking,,, lots of possibilities. Unless you want to get into learning to read codes, etc.... yep, the pros.
BTW, idling or even revving until the temperature comes up isn't enough. Chances are the exhaust system, particularly at the muffler end, hasn't fully warmed up. Exhaust gas plus moisture equals forming acids which leads to perforated exhaust plumbing. As long as the battery stays on a trickle charger, you're better off leaving the bike alone.
Not all who wander are lost. Which still leaves room for more than a few lost wanderers...
