Incandescent to LED rear lights

Yup! Number 3496. It's described in this previously-linked post. You can get the required bulbs (which have nice nickel-plate bases that will not corrode and seize in the sockets) from your local Honda dealer. Part number for the single-filament variety (replacing 1141, 1156, 1073, 7508, or P21W) is 34903-SF1-A01. Part number for the dual-filament variety (replacing 1016, 1034, 1157, 2057, 2357, 7528, or P21/5W in brake/tail or park/turn lights) is 34906-SL0-A01. Don't try to buy these bulbs in the aftermarket, and don't let the dealer sell you anything but a genuine Stanley-made Honda bulb; everything but the genuine Honda product is junk. The Honda (Stanley) items are ultrapremium bulbs with very long lifespan, corrosionproof nickelplate base, etc.



No, that's not correct. 1156 is a single-filament, 32-candlepower bulb. 1157 is a two-filament, 32/3-candlepower bulb. 3496 is a two-filament, 43/3.5-candlepower bulb.



If your brake lights are causing a "big" drain at idle, there's something the matter with your alternator. Yes, the early Chrysler charging systems are weak at idle, but not that weak!


Sorry, it's been awhile since I had to remember bulb numbers, but I know there is a different number than the 1157 that was brighter (but drew more amps too)
Not a big drain in my case but I have seen the headlight on some cars get dimmer with the brakelights on. (Mine is a brand new dual field 65 amp with all new grounds)
I don't run amplifiers or any non stock stuff except a CD/FM stereo
Dangit, now you have me curious Dan.
I'm going to have to go get two of 3496 those bulbs and chk out the difference between them and the LED's as far as amp draw and off axis refraction.
If I end up with amber lights in place of my backups I may never forgive you.
