The LED will be quite a drain on simple AA batteries however if you use a 12 to 22 ohm resistor you will still have VERY bright lights but at lower current. You will need a 1W resistor (minumum - best use 2W).
if you use the LED alone directly on the AA battery, it will be a drain on the battery. The LED should be accompanied by an appropriate resistor. check on the book below and you will have all the information about LED wiring

How much space do you have available? A single series resistor (better two, one for each headlight LED) may be the smallest in volume, but far more efficient would be a current regulating LED driver (with minimum value balancing resistors in series to each LED), or two current regulating LED drivers.
I'm not aware of all the modules out there these days, nor how much available space you have in the car housing, but I might get something like this "260mA No Pin" style:

There are more versatile drivers but their size grows above this tiny module above, fairly quickly.
Then there's drivers meant for flashlights, but those already set for as low as 1W (opposed to hacking it to get there) are somewhat rarer these days, but you could use either a buck regulator to power the two LEDs in parallel, or a boost regulator to power them in series. Any of these options would give better efficiency than using resistors, though as someone already mentioned, 2 x 1W headlights seems like a disproportionate load on an R/C vehicle that only uses a mere 4 x AA cell battery to power it.
